Alex Installation Problems

Okay, so I've been playing RTW for a few months and decided that I wanted to use Alex.exe to get better AI because the AI just isn't challenging enough. When I tried to do it, I couldn't find the .exe. My computer still shows RTW Alex as being installed, but I can't find the location folder either and it's taking 5 gigs of my HD space, so at the least I'd like to delete it or reinstall.

It might help if I explain how I installed EB. I had RTW for a few years, so I deleted RTW and BI, but not Alex because I bought it online and didn't know how to reinstall it later. I then reinstalled RTW and BI and then put EB over them, but now I have the Alex problem. Any suggestions on how to delete the file and then reinstall or at least just delete Alex so I can have more than 3 gigs left on my precious little HD?
