Installation steps:
1. Install Wolfenstein: Enemy Territory 2.55 onto your computer, leave the default destination. (C:\Program Files\Wolfenstein - Enemy Territory)
2. Run the Wolfenstein: Enemy Territory 2.60 Patch which will automatically patch the game.
3. Open the 2.60b patch folder, go into the win32 folder, run ET.exe and EXTRACT to desktop.
4. Go into the newly extracted folder where the ET.exe and ETDED.exe were, highlight and copy them.
5. Go to where you installed the actual game (C:\Program Files\Wolfenstein - Enemy Territory) and paste them into that folder and press yes to overwrite what was there previously.
6. Wolfenstein is complete, so test if it works by getting into a game and playing, as most problems with TC:E occur by a failed installation of Wolfenstein.
7. If you can't get in a game I suggest uninstalling and trying to re-install again.
8. Install True Combat Elite v0.49 and it will default be put into your Wolfenstein program folder. There will now be a folder called tcetest.
9. Extract the True Combat Elite v0.49b patch to the tcetest folder inside your Wolfenstein program folder. (C:\Program Files\Wolfenstein - Enemy Territory\tcetest)
10. You are set to play, run the game and put all the settings you want.
maybe a mod could move it to the proper section for you
