The absolute fool-proof way of installing this mod:
Download the mod. It comes in an archive that you can open with several programs, most common one being winrar. Open the archive, and extract the folder EAW-Re.
Somewhere on your computer there is a folder that holds all the Forces of corruption files, named "Star Wars Empire at War Forces of Corruption" Find it.
If you installed mods before, then there'll already be an extra folder inside the FoC directory called Mods, if not, create it. Drop EAW-Re in that Mods folder.
So it'll look like Star Wars Empire at War Forces of Corruption/Mods/EAW-Re
Open the EAW-Re folder. Inside is a shortcut which works if you installed the mod to C:\Program Files (x86)\LucasArts\Star Wars Empire at War Forces of Corruption\Mods\EAW-Re If it doesn't work, right click the shortcut, go to properties, and edit both target paths to where ever you have your game installed. Don't forget to keep the modpath otherwise it'll just start the regular game.
All steam related comments will be removed, read you lazy pricks.
Got a problem with AI? Try a reinstall of the game. AI works fine with a clean FoC and has been tested by me personally. Still doesn't work? Figure out what is causing the issue, don't ask me, I've got no clue what you did to your game.
