To fix the unrar9x.dll error without downloading any third-party files, you must repair or re-register the existing files on your system. This error usually happens when WinRAR or another extraction program loses its connection to the file, or when the file becomes corrupted.

Solution 1: Re-register the DLL File

Windows can sometimes lose track of DLL files. You can force the system to recognize it again using the Command Prompt.

  1. Press the Windows Key, type cmd, right-click Command Prompt, and select Run as administrator.
  2. Type regsvr32 /u unrar9x.dll and press Enter to unregister the file.
  3. Type regsvr32 unrar9x.dll and press Enter to re-register the file.
  4. Restart your computer.

Solution 2: Reinstall WinRAR (Safest Method)

Since unrar9x.dll is an official component of WinRAR, the safest way to restore it without downloading random internet files is to use the official installer already on your PC, or reinstall the app.

  1. Open the Control Panel and go to Programs and Features.
  2. Find WinRAR in the list and click Uninstall.
  3. Restart your PC.
  4. Run your original WinRAR installation setup file to install a clean copy.

Solution 3: Run System File Checker (SFC)

If the DLL file was altered by a system crash, Windows can repair it automatically using built-in system tools.

  1. Open Command Prompt as an administrator.
  2. Type sfc /scannow and press Enter.
  3. Wait for the scan to reach 100% completion.
  4. Restart your computer if Windows found and repaired corrupted files.

Solution 4: Restore from the Recycle Bin

If you accidentally deleted the file recently, it might still be in your trash.

  1. Open the Recycle Bin on your desktop.
  2. Type unrar9x.dll into the search bar in the top-right corner.
  3. If found, right-click the file and click Restore.
