Unarc.dll returned error code: 11 when installing the game

Unarc.dll returned error code -11

Error 11 states that the archive that was downloaded needs to be checked with a checksum before launching. This figure tells us what files and how many were included in the archive. If it does not match, then we will receive error 11 of the unarc.dll file.

Update the hash of the torrent file - if the file was downloaded using it. Be sure to check the hash amount on the site where the download was made.

Usually error 11 is associated with the inability to write data to the disk. It may be full or not writable at the moment.

Unarc.dll returned error code -12

In the case of error 12, as in 11, the problem is the hash amount. But in this case, unarc.dll complains about forcibly changing the integrity of the archive and the file itself that is currently involved.

• At the moment, the file from the archive may be occupied by an antivirus that is scanning it. Apparently the installer ignored this fact.
• Close the torrent program. It may currently be distributing a problematic archive component. If several programs interact with the file at the same time, error 12 will appear.
• Uncompress the file that the installer is trying to install.

Unarc.dll error code -14

The error means that the installation sector is blocked by a software application. This means that the file is currently busy and cannot be unpacked. This can occur if the archive hash does not match or is incorrectly packaged.

• Check the integrity of the installation file. Files may have been missed during download. If it is the game installer, perhaps the activator is the root of the problem.
• The antivirus could remove a malicious file from the archive, thereby damaging the integrity of the shared file.

Nature of the failure

The error “Unarc.dll returned error code: -14” indicates that the installation sector is blocked. In other words, at this particular moment the file is occupied by other software and cannot be unpacked correctly. This failure occurs due to a mismatch of amounts or due to irresponsible archiving by the developer.

If the error text contains the phrase “failed CRC check,” then the probable cause of the problem is related to damage to the archive file. To get out of this situation, you will have to find another source or check how correctly the download of the files used was completed.

If the notification contains the phrase “decompression failed,” we can safely say that the cause of the failure lies in the system itself - there are no problems with the archive, and there is no need to download it again.

Unarc.dll returned error code -2

If unarc.dll returned error code 2, this means that the archive is damaged. A violation of integrity could occur when certain sectors of the installation are used together.

• During unpacking/installation, disable your antivirus or pause it. This will make it easier for unpacking systems to interact.
• Remove the downloaded archive/file from your browser or torrent downloads.
• Leave the file distribution. This will unlock and expand access for the installer app.

What is this file?

Users can learn about this file during the installation of a program or any game. To save space, installer creators pack archive files. If the installation fails, you will see a message that unarc.dll returned error code 7. The failure index may change depending on the version of the archive and files, but the essence of the problem remains the same. In some cases, the reason is damage or absence of the mentioned file.

However, it is not always possible to fix the error by reinstalling the library. Read on for more information about all situations.

How to download and install unarc.dll

Let's move on to reviewing the instructions for installing the DLL file into the system. You need to follow all the steps from the instructions:

1. Download the archive with the library from the link at the bottom of the page, and unzip the file to your hard drive. Right-click to open the file’s context menu and select “Copy.” You can also use the hotkeys Ctrl+C.

1. Now go to the system partition of the disk. If 32-bit Windows is installed on your PC, then open the directory called System. On 64-bit OSes, you need to go to the SysWOW64 folder. Then right-click on an empty space and select “Paste” from the context menu. The procedure can be performed by pressing Ctrl+V.

1. If the folder already contains an old or damaged version of the library, select the option to replace the files. Copying will take no more than a few seconds.

1. Now, through the command line running as administrator, enter the request regsvrexe and, separated by a space, specify the full path to the inserted library. Start registering the file using the Enter key.

You can also register the library using the same command, but through the Run application. Launch the program using the Win+R combination.

Now check the functionality of the archive or game installer. If the error situation persists, the problem is not with the DLL. Test the following tips one by one:

• download and test another program or game installer;
• check your computer for viruses;
• increase the virtual page file through Windows settings;
• reinstall existing archivers;
• When setting up the installation, check that there are no Cyrillic characters in the folder names.

If the described options do not help, test your RAM for bad blocks. If you do not have the testing skills, seek help from specialists.

Unarc.dll returned error code -6

If you received error 6 when installing the game, this means that part of the archive was damaged or deleted during the installation process. This is done both by the system itself and by the installer to free up resources.

• Check the free space on your hard drive. Usually during the installation process it is used 2 times more than the file itself weighs.
• Free up more RAM. If the installer is equipped with graphic elements, an error may occur when loading them.
• Temporarily stop your antivirus. It will not scan the files live and they will become available.

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, the game itself was already broken (pirated version) or corrupted during analysis by your antivirus .

1. The solution is to download the file again, 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 that is to blame in 90% of cases.

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 when unpacking unarc.dll” . For such situations, it is better to try several archivers.

1. Install two or three archivers with the best capabilities 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 alphabet 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 practically 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 it 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.

When you try to unpack a large archive, “error code No. 1,2,3, etc.” will appear.

Also, very often the source of the problem can be RAM. It is recommended to check it using special utilities, such as Memtest86

• Check if you have the necessary space on your hard drive; if not, then remove all unnecessary programs.

And here is a short video instruction on how to download the unarc.dll library file directly.
