This should help you get ET running on Windows 7. If i forgot something feel free to correct me.
(Note: reworked the article and skipped the patching part. If you follow this article you will download yourself a already patched 2.6b version of this game. There are still 2.55 and 2.6 versions floating around the web. This article will not show how to patch from e.g. 2.55 to 2.6b).
First get yourself the game. Download it here: http://www.wolffiles.de/index.php?filebase&fid=17
Next you need to install what you just downloaded in a directory where you got full admin privileges. By default a directory like C:\Users\MyUserName\MyWetInstallHere should do the trick.
After the installation it might ask you if it should reinstall, because something probably could have been gone wrong. Simply click ‘no’. We already did install the game correctly, so there is no need to reinstall.
Because Punkbuster (the Anti-Cheat-Software) dropped support, you need to download yourself an etkey from etkey.org, otherwise you will get kicked or your xp won’t save on certain servers. Download it here: http://etkey.org/ Click on ‘Get an ETKEY’, save the file, then copy paste it into your etmain folder (etmain is located in your ET installation path).
Start the ET process with administrator rights and make yourself a profile. Make sure your connection settings are set correct. I have Lan/Cable/xDSL.
(Starting ET with administrator rights goes with righ-click on et.exe, and there choose ‘start as admin’.
Make sure your firewall lets ET connect to the internet.
