How to Fix Unarcdll Returned An Error Code 14 When Installing Games
Unarcdll is a dynamic link library (DLL) file that is used by some games and programs to decompress files during installation. Sometimes, you may encounter an error message like this when installing a game or program:
An error occurred while decompressing Archive header is corrupt! Unarc.dll returned an error code: -14
This error can be caused by various factors, such as low disk space, corrupted files, insufficient virtual memory, antivirus interference, or faulty hardware. In this article, we will show you some possible solutions to fix this error and install your game or program successfully.
Solution 1: Increase Your Virtual RAM
Virtual RAM is a portion of your hard disk that acts as an extension of your physical RAM. It can help improve your system performance and prevent memory-related errors. Virtual RAM should be twice your real RAM. For example, if you have 4 GB (4096 MB) of RAM, you should set your virtual RAM to 8192 MB[^1^]. Here are the steps to increase your virtual RAM:
Right-click on the Start menu and select Settings.
Click on System and then on About.
Under Related settings, click on Advanced system settings.
On the System Properties window, click on the Advanced tab and then on Settings under Performance.
On the Performance Options window, click on the Advanced tab and then on Change under Virtual memory.
Uncheck the box that says Automatically manage paging file size for all drives.
Select your drive where Windows is installed (usually C:) and click on Custom size.
Enter the initial size and maximum size in MB according to your RAM size. For example, if you have 4 GB of RAM, enter 4096 for both fields.
Click on Set and then on OK.
Restart your computer and try installing your game or program again.
Solution 2: Restore Corrupted Files
Sometimes, the unarc.dll file or other files related to the game or program may get corrupted due to various reasons, such as power outage, virus infection, or disk errors. This can cause the unarc.dll error when installing the game or program. To fix this, you can try restoring the corrupted files using the System File Checker (SFC) tool or the Deployment Image Servicing and Management (DISM) tool. These are built-in Windows tools that can scan and repair system files. Here are the steps to use them:
Type cmd in the search box and right-click on Command Prompt. Select Run as administrator.
Type sfc /scannow and press Enter. This will scan and repair any corrupted system files.
If the SFC tool finds any errors but cannot fix them, type dism /online /cleanup-image /restorehealth and press Enter. This will scan and repair any corrupted Windows image files.
Wait for the process to complete and restart your computer.
Try installing your game or program again.
Solution 3: Create Disk Space
The unarc.dll error can also occur if you don't have enough disk space to install your game or program. To fix this, you can try deleting some unnecessary files or moving them to another drive. You can also use the Disk Cleanup tool to free up some space. Here are the steps to use it:
Type disk cleanup in the search box and select Disk Cleanup.
Select your drive where Windows is installed (usually C:) and click on OK.
Select the files that you want to delete, such as Temporary files, Recycle Bin, Thumbnails, etc.
Click on Clean up system files and select more files that you want to delete, such as Windows Update Cleanup, Previous Windows installation(s), etc.
Click on OK and wait for the process to complete.
Try installing your game or program again.
