How can I get rid of uninstalled games that are still there hiding somewhere?

So basically I torrented and installed cracked sims 2 games, but I regretted my decision and decided to uninstall and buy them legit instead.

So I uninstalled, got rid of all the files and tried installing the legit versions. I'm missing a few of the expansion packs and intended to play without them, however when the launcher comes up it says the missing expansion packs are still there. It's all causing an error when I try to play and won't launch.

So I went to uninstall and delete everything to try and start over, I uninstalled all the expansion packs but can't uninstall the base game as it says there are other expansion packs still installed that must be uninstalled first.

I can not find these files ANYWHERE! I used daemon tools to install, I deleted all the images from daemon tools, and uninstall daemon tools, I've scanned through my comp for bad files and done everything I can think to do.

Any ideas, suggestions and help on trying to get rid of these phantom expansion packs would be greatly appreciated.

I'm running windows 7.

Thank you.
