What to do if you get an isdone dll error. Solutions related to DLL files

Game lovers always try to keep up with the latest innovations in order to install the software on time, but there are often situations when anticipation gives way to disappointment.

What does the ISDone.dll error look like and what does it mean?

The ISDone.dll error says that our long-awaited toy cannot be unpacked, and therefore cannot be installed due to certain problems. If a malfunction occurs during installation, you should first look for the cause of the malfunction. The solution to the unzipping error when activating the game will directly depend on the reasons for its occurrence.

Causes of ISDone.dll error

Let's try to look at the most common causes of problems so that we can fix them.

Antivirus

If your computer scares you with an isdone dll error during installation, the reason may be an antivirus program that does not perceive it as malicious. It’s very easy to get rid of this problem; you just need to disable the antivirus program, unpack and install the file, and after rebooting, turn on the protection again. You can download the antivirus on our website.

But in some cases, the antivirus tries to treat what it thinks is a malicious file without asking for consent. The result of such intervention may be damage to the archive, and the game will have to be re-uploaded.

Path to element

Very often the cause of the error is an incorrectly specified path to the element, when the name of the folder into which the game was uploaded is written in Cyrillic. The solution to unzipping failure when installing games for such a case is distinguished by its simplicity. Here it is enough to simply rename the folders, writing the name in English letters.

Fraud

If you see a “CRC check” message, which means that the file integrity has been compromised and your game is missing files.

Note: But it can be even worse when the file simply contains a virus that can harm the system.

In any case, we fix problems when installing games in this way:

1. We dump the archive onto a flash drive;
2. we try to install the game on another computer, if it doesn’t work, it means that it is really damaged;
3. We are looking for a reliable source for downloading new high-quality software;
4. If you are sure of the source and the game program itself, but it still does not unpack, then the problem is in the computer itself.

Failure code and its types

ISDone.dll is a library responsible for unpacking and preparing game files for installation. The library returns a failure code if it cannot unpack, while the notification text contains data about damage to the archived components, when it is insufficiently downloaded, bitten or with a virus. In all other cases, the program may return a notification label with the numbers 1, 7, 6, 14 or 12, all of these codes indicate problems that need to be looked for in the computer.

Checking on a third-party personal computer

Many people, after the library returns an error, dump the archive onto a flash drive and check it on other computer equipment.

This measure is relevant when the text of the notification does not contain information about file damage.

RAM

It happens when the archive cannot be unpacked due to the fact that there is not enough space on the hard drive. Many users make the mistake of believing that there is enough space for activation, the size of the archive itself. In fact, the archive contains not only the game itself, but also temporary file materials that will be used for installation and deleted after installation.

Sometimes the cause of trouble is that the RAM has flaws, but such a problem can be detected even before loading the material, because it is characterized by freezing of the computer. Here you will have to test your memory or seek help from a specialist.

No archiver

Sometimes the reason for the error is the lack of an archiver, with the help of which unarchiving is performed.

In this case, it is necessary to launch the archiver, but you should keep in mind that if you have already used archives on your computer and you succeeded, then you have an archiver and the problem is not its absence.

If the page file is small or disabled

You can check the paging this way:

1. open the control panel;
2. go to the system and protection section;
3. select the “system” item;
4. open additional parameters;
5. click on the “advanced” item;
6. open the performance settings menu;
7. increase the parameters by several units;
8. Let's try to unzip the game again.

How to fix isdone dll error during installation

If you get an isdone dll error at startup, you can try to fix it using the following methods.

Disabling antivirus

This is the easiest way to unpack and run the game, but if we are talking about a damaged file, and not about incompatibility with the operating system, it may contain a virus and leaving the system unprotected, you can harm it.

Note: It is important to remember that if you use disabling the antivirus program, you should activate it not after unzipping and activating it, but after rebooting.

Rename folder

This will help if you downloaded the archive to a folder whose name is in Cyrillic. In this case, the library will return a notification with code 7, which indicates an incorrect path to the element.

Experienced gamers make sure that the folders containing game material have names written in English.

Download isdone.dll and install

Many sources claim that this method is very effective, although practice shows that when installing isdone.dll, only the fault notification code changes. And for some, this method of fixing unzipping problems turns into real problems.

The fact is that in many cases, under the guise of the desired material, spyware is hidden, which, after its installation, will transfer your personal data to certain sources.

In which games is the error common?

Unzipping problems can occur when running any video game that is large in size. But the point here is not only in the parameters of the installation elements, but also in the quality of the installation elements.

When choosing a gaming program, it is better to purchase high-quality licensed products; they are easy to unpack and install, provided that you do not have problems with computer memory. The antivirus program does not respond to such games; they are always intact and do not contain viruses.

If you still have questions, this video will help you understand the reasons and principles for correcting problems with unzipping game materials.

Having managed to detect and fix the problem, you will be able to please yourself with a new gaming product.

Today we will talk about the ISDone.dll problem, which occurs when you try to install a game on Windows 7, 8 or 10. We will tell you why the error occurs and how to fix the problem.

Users of versions of Windows 7 and 8 may suddenly see the most unpleasant inscription - "ISDone.dll encountered an error while unpacking" Next, the reason is indicated: “The archive is damaged” or “It is impossible to read data” and a specific number is indicated in "Unarc.dll returned an error code."

Why does it occur when trying to extract files from an archive, even taking into account the condition of downloading from a reliable source? The answer can only be to check the entire computer for functionality, namely, to perform certain actions one by one.

What should I do to eliminate ISDone.dll?

Installing a new game is a very exciting moment, especially if it's part Assassin's Creed, legendary series Resident Evil, GTA 5, FIFA, Sims, Fallout 4 etc. By the way, this bug is typical for graphically complex games on Windows 7/8/10 and 64 bit.

First option

1. The initial step should be to decide to disable the antivirus; all its processes should be deactivated. This helps in many cases, especially with antivirus Dr.Web.
2. The first point didn’t help, then let’s move on to the second. Here you need to be careful about the path where the file is located. The reason lies in folder name storage places. The name must be in English only; the use of the Cyrillic alphabet is not acceptable. If the folder is called Games, then it should be replaced with Game. An easier way would be to move the file to drive C.
3. What you should not do is try to download ISDone.dll from the Internet. Replacing it in most cases does not bring results, but catch a virus It's very possible. To begin with, try all the suggested methods, only resort to this point as a last resort.

Second option if the first doesn’t help

1. The installation was unsuccessful. Take a flash drive and transfer the file to it. Next, try checking the functionality on another computer. If everything works, then start studying the system indicators on your PC.
2. The problem lies to a lesser extent in the operating system; in most cases, faulty boards on the motherboard are detected. The first object for diagnosis should be RAM memory.
3. RAM, as the main type of isdone.dll error, occurs more often. The faulty memory module should be identified one by one, that is, when unpacking the file, remove the components. If the unpacking was successful when removing the memory module, then the problem has been detected.

These actions largely have a positive effect on resolving the issue with the isdone.dll error. The last additional item could be downloading the official unpacker programs, subject to checking the computer and verifying its performance. If the file turns out to be damaged, the unpacker can partially fix it, although there are not many guarantees.

And here Video instruction to fix the bug using auxiliary applications. Judging by the reviews - works.

The notification “ISDone.dll - an error occurred during unpacking” is not a death sentence, it is only a reason to check the computer for full functionality. You should download only from reliable Internet sources, then with this problem you can safely say that the PC is to blame. You should also download the isdone.dll library only with guarantees from the developer, if everything you tried did not help.

In contact with

Today we will discuss how to fix ISDone.dll component failure. “An error occurred while unpacking” - a message of this type often occurs among users of the Windows 8 and 7 operating systems.

Antivirus

An error like “ISDone.dll - an error occurred during unpacking” can occur when unpacking an archive downloaded from the Internet, or when installing games with the Innosetup installation application. To solve this problem, first of all, disable the antivirus and repeat the process again. If this method works, you won’t have to do anything else, the problem will be fixed.

Path to element

An error related to ISDone.dll cannot always be resolved by disabling the antivirus. A possible cause is the path to the material if it contains characters of non-Latin origin. In other words, if the directory name is in Russian, for example, C:\Games, we need to rename it. The path in our case should look like this: C:\Games. The error “ISDone.dll: an error occurred while unpacking” may recur. Perhaps the path to the element being processed is very long, and non-Latin characters appear several times in it. In this case, transfer the file to the root directory of the main drive C or another suitable location with a short address.

Fraud

Please note that to resolve the issue of how to fix ISDone.dll, the Internet may recommend that you download a file with the same name. Next you will be asked to install it in the system directory. You can also find programs that supposedly correct these errors. In reality, such methods will not work. We do not recommend that you download any files or applications, as they most likely carry a virus. At the moment, no tools have been created to solve this problem, which can simply be downloaded from the Internet. Only manual settings can correct the situation. Be careful and don't fall into the hands of scammers!

Failure code and its types

Now let’s look at what to do if we get the error “ISDone.dll - the archive is damaged.” This failure may be accompanied by the following codes: 12, 7, 6. A message in English may also be displayed: "ERROR: archive data corrupted". It is possible that a failure with code “1” may occur. An error related to ISDone.dll often occurs when installing Assassin’s creed, Day One, Crysis Warhead, Resident Evil. A crash may also occur during the installation of other gaming applications. We will talk about how to eliminate it in such a situation in the next section of this material.

Checking on a third-party personal computer

The failure described in this material may be accompanied by various messages. One of them looks like this: “ISDone.dll: This file is used by the installer for unpacking.” To fix the problem, you need to follow a series of steps that may seem very strange at first glance, but the effectiveness of this approach is very high.

We move the file in use to a third-party computer. For this we use a USB flash drive or a local network. If after transfer the file works properly, then the problem lies in the first computer. Note that there are several reasons for this situation, but the main ones include memory and system problems.

If a similar error appears on another computer, download the file in question directly from the previously used source on the Internet. Unpack or install the element. So, if the error repeats during the transfer, download the file to the new PC, but from the same source, and deploy it there. If these actions lead to stable operation of the package on the second computer, most likely the first one does not have enough RAM to play the element.

To solve the problem, you need to replace the PC hardware, namely, install a more modern RAM module. It should be noted that the failure itself “ISDone.dll - an error occurred during unpacking” is most often caused by problems with the hardware; problems directly in the Windows operating system rarely lead to this result.

If the above methods do not work, download the file from an alternative source. We can also use an application called "Universal Unpacker". In the original - Universal Extractor. This is a free program. Using this solution, in some cases it is possible to unpack installed archives that appear damaged to the system.

RAM

If it is determined that the cause of the “ISDone.dll file is damaged” failure is RAM, disable the corresponding modules one by one. We launch the file being processed after removing each of the memory elements. PC disassembly operations should only be carried out in the off state. We strongly recommend that you entrust this operation to experts. This approach requires a lot of time, extreme caution and professionalism, but in some cases it can be effective. As a result, the file can work. However, it is better to purchase new ones if possible.

Management

In conclusion, we will provide step-by-step instructions in which we will describe the key steps in resolving the “ISDone.dll - an error occurred during unpacking” error.

1. Disable anti-virus protection.

2. Please pay attention to the explanations following the word ERROR.

3. Download the package again or from another source.

4. Update the archiver used to the latest version.

5. We use a licensed version of the software.

6. Install RAR.

7. Install 7-zip.

8. Rename in Latin letters all the folders that are in the path to the application.

9. Increase the size of the paging file.

10. Reinstall the operating system.

11. Change memory modules.

If you encounter the error described above, remember that although it refers to archive corruption, 99 percent of the time the archive is fine. In this case, identifying the causes of the error by its code is ineffective. If the failure description says the following: “failed CRC Check,” this may indicate actual damage to the archive. If the error note says “Decompression failed,” the reason lies in the PC you are using. We have already discussed above how to deal with this situation.

In step 9 of the instructions, the swap file was mentioned. To work with it, go to the system properties. Open the “Advanced” section. We use the “Options” function. In the new window, go to the “Advanced” tab again. Next, in the “Virtual Memory” item, use the “Change” function. Uncheck the automatic volume detection box. Specify a local disk for its placement. We use any volume except the system one, where there is a lot of free space. Specify the maximum value equal to the size of RAM and click the “Set” button. We save the parameters.

Sometimes when installing a game on Windows 7, 8, 10, the isdone.dll error pops up. The message reads "Unarc.dll returned error code:" followed by an error number, usually 1,6,7,12,14. At the bottom of the window the cause of the problem is written; if it is “failed CRC Check”, then most likely the installation file is damaged and should be downloaded again. Errors like “archive data corrupted (decompression fails)” are more common. In this case, the problem is in the computer and the error may appear in the future when installing another game. The isdone.dll file is one of the libraries of the Inno Setup package, which is responsible for unpacking archives. The error usually occurs when installing repacks, since their creators often resort to exotic compression algorithms. Also, the files are too large and the system cannot unpack them.

You can fix the isdone.dll error like this:

• Download the new version of the archiver
• Check if there is enough free disk space
• Rename installation path
• Download isdone.dll

First of all, try downloading the archiver. The free program 7zip works well, but WinRar and WinZip work just as well. For reliability, you can install several different archivers. Sometimes, if an error occurs during unpacking or installation, you need to look at the path to the archive and the installation directory. If it contains Russian names, then they should be replaced with English ones - this may solve the problem.

Sometimes you can fix the error by temporarily disabling the firewall and antivirus, but this way you risk catching a virus. You can also try installing the problematic file on another computer, if you have the opportunity. If all else fails, then you can download isdone.dll from us for Windows 7/8/10 x64 or x32. The downloaded file should be placed in the system folder, which depends on your version of Windows. It's worth noting that this rarely solves the problem, but it can be useful in some cases. Now that you know what to do to fix the isdone.dll error, one of these methods will certainly help.

When you wait a long time for the release of your favorite game, you download it, sometimes suddenly the message “ISDone.dll: an error occurred during unpacking” and a code next to it appears on the screen. The first thing people do is get confused, upset and don’t know how to deal with such a problem. In fact, there are many ways to correct the situation, and in an hour or two of work you can get your computer back into working condition.

Description of the problem

Most often, the message that an error occurred during unpacking in the ISDone.dll component does not appear when installing a specific project. The problem is observed when unpacking several games, and this already means that you need to gradually look for a solution in your system. The error itself with a similar code also has different inscriptions that indicate a specific reason. You should read them carefully, and then eliminating the problem will go even faster. In any case, the reasons are conditionally divided into two categories: those related to the file itself and system problems. Based on this, it is worth looking for a solution. It is also worth noting that the numbering of codes does not have much influence here, because you will have to check the most obvious reasons one by one without this.

Client verification

If the user sees on his monitor that an error occurred during unpacking in the ISDone.dll system, then he should immediately transfer this archive to a portable drive. If the installation on another device proceeds without any problems, then you should move on to cleaning your own system. Often the result is the same on all computers, indicating corrupted files. It is especially worth paying attention to the presence in the error window of the words CRC check or an indication that there is no integrity in all documents. The reason most often lies in the fact that the user did not completely download the archive from the file hosting service. It is also possible that there was a virus on the computer that managed to ruin the installation. The solution here is simple: completely download the data archive, and then calmly begin the process of introducing the game. It is possible that the selected download link already contains a broken file. Then you should simply use another site or distribution source.

Archiver

For beginners who are just beginning to learn all the intricacies of installing games, the message that an error occurred during unpacking in the ISDone.dll structure is confusing. This shouldn’t happen, because the main thing to remember is: always check the text that appears on the screen in the error window. It may simply say that there is no unpacking program on the computer. If the archiver itself is damaged, it may not see some files. The solution here is to re-download all the most popular applications of this kind. If you have 7-Z, WinRar and WinZip on your computer, then this problem will not arise in the future. Even for simple reinsurance, it is better to have these three archivers. Then the user will be sure that the error does not occur for this reason.

Most common case

As soon as a user discovers on his computer that an error 7 occurred during unpacking (or with another numeric code) in the ISDone.dll component, then he should immediately begin cleaning the system from viruses. Not all PC owners can afford to have a licensed antivirus that will block all malicious programs using a firewall. That is why all sorts of documents disguised as useful information and applications appear on the computer. As a result, the system begins to work in a critical state, many files are damaged before they even fully appear on the computer (as is the case with the game archive).

In order to reinsure yourself in the future or solve the problem, now you need to use free healing utilities. An example could be a small program that is distributed free of charge on the Dr.Web website. After downloading, launch it and the scanning will begin. Specialists in this field always update the database with new algorithms, so a high-quality search is guaranteed. The process will take from an hour to three, depending on the amount of information on the computer. If viruses are found, this means that this was the reason that an error occurred during unpacking in the ISDone.dll system (1 - code numbering). Send malicious files to quarantine and rest assured that your system is safe.

Funny incident

When users encounter errors with different codes, they immediately think that serious problems have been detected in their system. This frightens them and causes them to panic. In fact, the solution lies right on the surface. In one of the installation points, you must specify the path from the folder directory where exactly all the files will go. Some installers don't like it too much if the name is given in Cyrillic. They do not perceive anything other than Latin, and because of this it turns out that an error occurred during unpacking in the ISDone.dll component (code 6). The solution here couldn’t be simpler, because all you have to do is try to install the game again. At the same time, do not forget to be attentive. Check the language bar and the presence of Russian characters in the folder names. A good example is the letter “c”, which looks the same in English and is located on one key. This is a common problem that occurs due to user negligence.

Inner memory

When a user often installs computer games and likes to collect them, then memory problems begin. Only every fifth user has the habit of checking how much space is left on the hard drive and what should be deleted from the files there. Most people believe that it is unrealistic to occupy five thousand gigabytes, and do not take into account that current projects require at least twenty of the five hundred present. It turns out that problems may begin as early as the tenth installation. If the message “ISDone.dll (12) an error occurred during unpacking” appears on the screen, then immediately check the hard drive. If there is not enough space, then we simply clean it, free up space and start installing the game again. In this case, it is better not to continue the interrupted process, because in the future you may encounter other problems that arise.

RAM

By its nature, a parameter such as RAM rarely alerts you to problems within the system. A user can use the installed Windows package for months without any problems, but problems will still exist. They will make themselves felt most often in such cases as installing a game. Signals of problems with RAM will be the occurrence of a critical error in the form of a blue screen and the device rebooting on its own. Even if this does not happen, then it is worth paying attention to the performance of the operating system. Detection of frequent freezes, even for a second, may indicate that diagnostics are necessary. You can do this by downloading the application or making an installation disk (flash drive). The check will give results and it will be possible to immediately eliminate the detected problems.

Swap file

There are cases when an error occurred in the ISDone.dll structure during unpacking (code 5) due to the fact that the paging file was turned off. This could happen due to a critical error or manually due to user negligence. To restore its operation, it is necessary to perform a number of operations. First, in the “Start” menu, find “Control Panel” and select “System and Security” there. In the menu that opens on the right there will be a clickable line “Advanced system parameters”. Go to it and open the “Advanced” tab, where you will see the “Performance Options” item. Here you can change the size, enable or disable the paging file. At the moment, there is constant debate between analysts about what it should be. It is recommended to change the standard value only by a small, fixed amount.

It is best when your computer never experiences any such problems. You can protect yourself from this. You shouldn’t wait when you’ve finally decided to install your favorite RPG and suddenly the “Skyrim: ISDone.dll error occurred while unpacking the component” window pops up. First of all, always monitor your memory, both internal and operating. Clean your PC from viruses and harmful documents. It’s better to make it a habit to regularly download utilities and check your device. After that, clean the registry and all sorts of junk from your computer. The caching process likes to leave behind a large number of unnecessary residual files after uninstallation, installation, and movement. Ultimately, just defragment the disks after a dozen operations. This will also free up memory and avoid many problems.
