How to fix Wolfenstein Enemy Territory ui_mp_x86 dll error?

When attempting to join an Enemy Territory server, you may encounter the “Game code (ui_mp_x86.dll) failed pure server” error. This error arises when one or more pk3 files within your Enemy Territory folder are corrupted or modified, potentially due to hacking attempts. Fortunately, several methods can be employed to address this issue and allow you to enjoy your gaming experience without any hiccups.

Running Enemy Territory as an Administrator

One of the primary solutions to this error is to run Enemy Territory with administrator privileges. To do this, follow these steps:

  5. Check the box for “Run this program as an administrator.”
  6. Launch the game.

Disabling User Account Control (UAC) on Windows Vista or Windows 7 Systems

If running the game as an administrator doesn’t resolve the issue, you can try disabling User Account Control (UAC) on your Windows Vista or Windows 7 system. Follow these steps:

  • Open the Control Panel.
  • Type “UAC” in the search box.
  • Click on “Turn User Account Control (UAC) on or off.”
  • Uncheck the checkbox for “Use User Account Control (UAC).”
  • Click “OK.”
  • Restart your computer.

Reinstalling Enemy Territory

If neither of the above solutions works, you may need to completely reinstall Enemy Territory. However, be sure to back up your etkey file before proceeding with the deletion and reinstallation process. Follow these steps:

  • Locate your etkey file and create a backup.
  • Uninstall Enemy Territory from your system.
  • Download a fresh copy of the game from a reliable source.
  • Install the game on your system.
  • Replace the etkey file in the newly installed Enemy Territory folder with the backed-up version.
