Before you upgrade: What to do if you are already using a pirate/warez or GOG key

From Unreal Tournament 2004 MiA Wiki

Warez Game Keys

We're aware that there are a number of warez/torrent/pirate copies of UT2004 on the internet. We have seen these game keys being widely used in the past.

Some people bought the game from GOG and never asked for their own unique CD key.

We also see cracked copies of the game using the Demo key on live servers.

We have found that when cheats or problem players are banned they will often start to use any keys they can find online. Where a problem player or cheat starts to cause problems on one of our servers we will ban the key they are using.

You can now get your own copy of the game for free, but first there are a couple of things you may need to do:

If you are running the 64 bit version of the game on Windows:

  1. Back up your copy of the game and the two registry keys below, if they exist
  2. Use regedit to rename or delete the old key you will find present in:
    1. Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Unreal Technology\Installed Apps\UT2004\CDKey or
    2. Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Unreal Technology\Installed Apps\UT2004\CDKey
  3. Continue to upgrade your copy of the game as detailed on this page.

If you are running Linux

  1. Back up your copy of the game and the contents of ~/.ut2004
  2. Delete your cdkey file which will be either in ~/.ut2004/System/cdkey or in the System folder of your UT2004 installation directory
  3. Continue to upgrade your copy of the game as detailed on this page.
