Im guessing it is installed in the default place for these instructions.
Download and open the file from Moddb
Then drag the AoTC folder and place it in
C:\Program Files\LucasArts\Star Wars Empire at War Forces of Corruption
or
C:\Program Files (x86)\LucasArts\Star Wars Empire at War Forces of Corruption (if you have a version of windows with two different program files folders.
Use the shortcut included. (Right click and view properties to make sure that it uses the folder location of the AoTC folder).
If you have it on Steam, I am not sure about how to help for that.
Im sorry that it isn't easier to install. We had to make do with what we had at the time.
