Solution 1: Reinstall Unarc.dll
One of the simplest ways to fix unarc.dll errors is to reinstall the file on your system. You can do this by following these steps:
Download unarc.dll from a reliable source, such as DLL-files.com. Make sure you download the correct version for your system (32 bit or 64 bit).
Locate the current unarc.dll file on your computer and rename it as unarc.bak.dll. You can find it in the %systemroot%\\System32 folder on 32 bit systems or in the %systemroot%\\SysWOW64 folder on 64 bit systems.
Copy the downloaded unarc.dll file and paste it in the same folder where you renamed the original file.
Restart your computer and try to run the program that needs unarc.dll again.
Solution 2: Register Unarc.dll with Regsvr32
Another possible solution for unarc.dll errors is to register the file with Regsvr32, a command-line utility that can register and unregister OLE controls, such as DLLs and ActiveX controls in the Windows Registry. To do this, follow these steps:
Open an elevated command prompt. To do this, click Start, type Command Prompt or cmd in the Search box, right-click Command Prompt, and then click Run as administrator.
Type the following command and press Enter: %systemroot%\\SysWOW64\\regsvr32 %systemroot%\\SysWOW64\\unarc.dll
You should see a message saying that unarc.dll was registered successfully.
Close the command prompt and try to run the program that needs unarc.dll again.
Solution 3: Check Your Disk Space and Archive Integrity
Sometimes unarc.dll errors can occur because there is not enough disk space to unpack the compressed archive or because the archive is corrupted or unreadable. To fix this, you can try these steps:
Make sure you have enough free space on your hard drive to extract the archive. You can check your disk space by right-clicking your drive in File Explorer and selecting Properties.
If you downloaded the archive from the internet, make sure it is not corrupted or incomplete. You can use a tool like WinRAR or 7-Zip to test the archive integrity and repair it if possible.
If you copied the archive from another source, such as a CD or a USB drive, make sure it is not damaged or scratched. You can try to copy it again or use another source if available.
If you have permission issues with extracting the archive, try to run the program as an administrator or change the destination folder to one that you have full access to.
