ISDone.dll and Unarc.dll errors can occur during the installation of games or other software. These errors are typically caused by a problem with the installation package or with the system's configuration.
Here are some steps you can try to fix these errors:
- Run the installer as an administrator: Right-click on the installer file and select "Run as administrator" from the context menu.
- Check for system updates: Make sure your operating system and drivers are up to date. Go to Settings > Update & Security > Windows Update and check for updates. You can also visit your computer manufacturer's website to download the latest drivers.
- Check your hard drive for errors: Run a disk check to see if there are any errors on your hard drive that might be causing the problem. To do this, go to This PC > Local Disk (C:) > Properties > Tools > Check.
- Disable antivirus software: Antivirus software can interfere with the installation process. Try disabling your antivirus software temporarily while you install the game or software.
- Clean up your system: Remove any unnecessary files and programs from your computer to free up disk space. You can use the Disk Cleanup tool to do this. Go to This PC > Local Disk (C:) > Properties > Disk Cleanup.
- Try a different installation package: If the error persists, try downloading a different installation package or a different version of the game or software.
- Replace the DLL files: If the error message specifically mentions ISDone.dll or Unarc.dll, you may need to replace these files. You can download these files from a trusted source and copy them to the system folder where they belong. Be careful when downloading DLL files as some sources may provide malicious files.
