Video: ISDone.dll encountered an error when unpacking Unarc.dll returned an error code

The situation is quite common: the unarc.dll error appears after downloading an archive or when trying to install a game downloaded from the Internet. This can happen on Windows 10, 8, Windows 7 and even Windows XP. After reading other people’s suggestions on how to solve the problem, I came across the fact that only in one case out of 10 an important option is indicated, which is the culprit in 50% of such cases. But let's take it in order.

Update 2016: before proceeding with the described methods to fix the unarc.dll error, I recommend performing two steps: disable the antivirus (including Windows Defender) and then try installing the game or program again - most often these simple steps help.

For this method we thank one of the readers under the nickname Konflikt, it’s worth checking, it is quite possible that the unarc.dll error is caused by the specified reason:

Attention to everyone who was not helped by all the above-described dances with a tambourine. The problem may lie in the folder in which the archive with this error is located! Make sure that there are no Russian letters in the path where the file is located (EXACTLY WHERE THE ARCHIVE IS, and not where you unpack it). For example, if the archive is in the “Games” folder, rename the folder to “Games”. It worked on Win 8.1 x64, it’s good that I didn’t get to the point of tinkering with the system unit.

Another option to fix the error

An option that is used by many, but helps few:

1. Download the unarc.dll library separately
2. We put it in System32, in a 64-bit system we also put it in SysWOW64
3. In the command line, enter regsvr32 unarc.dll, press Enter and restart the computer

We try again to unpack the file or install the game.

Provided that nothing has helped at this stage, and you don’t mind reinstalling Windows, you can do this. But keep in mind that most often this does not solve the problem. On one of the forums, a person writes that he reinstalled Windows four times, the unarc.dll error did not disappear... I wonder why four times?

If you tried everything, but the ISDone.dll or unarc.dll error remains

Now let’s move on to the saddest, but at the same time very common case that causes this error - problems with the computer’s RAM. You can use diagnostic utilities to test RAM, or you can also, provided that you have two or more memory modules, remove them one by one, turn on the computer, load the archive and try to unpack. If it works, then the problem is in the module that was removed, and if the unarc.dll error occurs again, move on to the next board.

And yet, a very rare situation that I once encountered: a person transferred archives to his flash drive, but they were not unpacked. In this case, the problem was precisely in the flash drive - so if you bring some files from outside without downloading them directly from the Internet, then it is quite possible that unarc.dll arises from a problematic media.

After downloading an archive containing the installer of a game, a message appears indicating that the archive is damaged: “Unarc.dll returned an error code...” A similar failure occurs during installation after unpacking performed using the Inno installer.

The error code can be indicated by a number from 1 to 14. But the archive may be in order. Let's look at different causes of errors and ways to fix them.

If you are a gamer, then you may sometimes encounter unarc.dll errors.

The message “unarc dll returned error code 1” indicates problems unpacking the archive. Usually in this case, unpacking on another device is performed without complications. The following options are possible:

1. The problem occurs due to the presence of a defender on the PC, which blocks the unpacking of the archive and the launch of the game/program. Therefore, you just need to disable the defender. Done this way:

• In Control Panel, search for Windows Defender.
• After launching the defender, go to the “Options” button.
• Disable the defender in the "Real-time protection" section.

Another antivirus may also block the program. Disable your antivirus temporarily, but remember that you will be putting your PC at risk.

1. The archive was damaged during download.

You can check its integrity in the Total Commander program. Go to “File”, click on “Check Archive”. If the program shows an error, download the file you need from another location.

Code 6

This error most often appears during the installation process of a program/game. If you receive the message “unarc dll returned error code 6,” please note that the cause is usually the hard drive. Check by copying the file to another medium (flash drive, disk). If the transfer is successful, it means that the problem is in your computer - its hard drive. We fix it by following the steps of the algorithm:

• Launch Command Prompt. When activating, select run as administrator.
• Enter “Chkdsk C: /F /R” into the command line - for the FAT file system, Chkdsk C: /F /R /B for the NTFS file system.
• Pressing "Enter" will run the command. Please note that checking and correcting the disc will take up to 5 hours.

There is a solution for such cases too. Since it is impossible to manually correct such failures (even if original libraries copied from another computer with a similar OS or downloaded from the Internet are integrated into the system), they must be restored. We do not consider rolling back the system, because the components could have been damaged quite a long time ago, and there is no checkpoint for recovery.

You can check the system with the sfc scannow command, which is entered in the appropriate console. The easiest way is to use special utilities like DLL Suite or Microsoft Fix It!, which will perform all operations automatically without user intervention.

Conclusion

To conclude the topic, it remains to add that the most common failures are precisely archived data errors, so it is better not to use various kinds of repacks, but to install the games you like or love using official distributions. Only in this case can we guarantee that the installation will be successful and that no problems will arise during the installation process.

Just in case, archiver programs should also be kept up to date, because new versions with which archives are created require more powerful compression using updated algorithms, and outdated modifications may not support such technologies.

Finally, issues related to damage to RAM sticks and any other physical failures were not considered here.

When extracting from the archive and installing repacks of pirated versions of video games and computer programs, users encounter errors with the unarc.dll library. This problem is common among gamers and appears on computers with Windows 7 and 8. The error code may be different, the main thing you should pay attention to is the notification text in the sign. If you see such an error, do not rush to download RePack games again or from another source, even if you see a message that the archive cannot be unpacked because it is damaged. In fact, there is a 99% chance that everything is fine with the game or program files. Here the matter is different. And to figure it out, you need to pay attention not to the error code, but to the message after ERROR.

This is how the error is described in this screenshot:

Cyrillic in the folder name

Incorrectly configured pagefile.sys (Windows swap file)

To do this, click on Win+R and enter the following command in the window: sysdm.cpl

RAM (random access memory)

Click Start and write “Diagnose computer memory problems.” Clicking on the icon will open a window:

Library downloaded to PC unarc.dll will not solve the problem, perhaps it will only change the error code number. If the methods we have discussed do not work, there is only one way out - to reinstall the system.

Post navigation

Avid gamers in our country very often have to face various problems when installing games. One of the problems is pop-up windows in the form of: "Unarc.dll returned error code: 11" or other code values ​​1, 5, 6, 7, 8. In general, the number does not make much difference. All these types of conflicts are eliminated by the same solutions. Next we will show you how to fix error code -11 when installing games.

What is this error code -11?

The first thing you should always pay attention to is downloaded file. Most likely, it is not licensed, which means it may contain a bunch of problems. Exactly "pirate" games become to blame for the impossibility of their installation. Extracting software from a downloaded archive comes with many risks, because the possibility of not completing the operation always remains. The same rule applies to torrent downloading itself.

Solution to "error code -11" in games

First, analyze the process of downloading the game onto your computer. Perhaps at some point the Internet connection failed and the file was not downloaded or the integrity of the file was compromised. In another situation myself the game was already broken(pirated version) or damaged during analysis by your antivirus.

1. The solution is to re-download the file, but first disable your antivirus.
2. Find an alternative to this software. Please refer to earlier versions or other download sources.

I think everything is simple here. It is the downloaded file in 90% cases is the fault.

Trying to unpack the archive

It is highly recommended that all users have several archivers on their PC. This is due to the fact that sometimes a particular archive cannot be opened, which is why the user may receive a notification "error unpacking unarc.dll". For such situations, it is better to try several archivers.

1. Install two or three archivers with the best features at once: WinRar, WinZip, 7-Z.
2. Try to open each of them one by one.

Sometimes this method helps players unpack games.

Russian letters on the way

Russian letters or Cyrillic Always conflicts with many utilities. Foreign programs cannot recognize such characters in their installation path. These strange characters are the cause of “returned error code: -11”. Although modern developments have almost eradicated this situation, the user still falls into such cases.

• Correct the name of the folder where you are going to install the game. For example, if the folder is called GTA 5 Online, then change to GTA 5 ONLINE.

In general, make it a habit to always write folder names on your computer in English.

Hard drive is full

Modern games are very impressive in size. At least remember the most popular series GTA 5. It will take up at least 65 GB of hard drive space. This situation is sometimes missed by users with weak PCs. As a result, it turns out that there is simply no free space. When you try to unpack a large archive, “error code No. 1,2,3, etc.” will appear.

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 making sure it is working. 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.
