I recently tried to play the sims 2 again. My most recent "expansion" was the University Life collection which included the University expansion, Ikea Stuff, and Teen Style Stuff but I remember having to launch the game via the Mansion and Garden stuff pack. I have Windows 7 and built my computer specifically for playing sims.

When I tried to run the game, it said "Some needed files were corrupted during the installation. Please reinstall this application."

Don't know how that happened. I haven't touched the game in several years but since then I've added and removed unrelated things from my computer a dozen times over. Maybe some files just got screwed up.

No big deal either way. I don't care about any saved games I had, I'll just uninstall and reinstall the game. But when I went to Programs and Features and right-clicked Mansion and Garden to uninstall it, nothing came up. In fact it's been 30 minutes now and nothing. I tried again just in case I miss clicked or something, but no. I don't know how else to uninstall a game.

So what do I do? I went through the uninstalling page on the wiki and even clicked the link to manually uninstalling but it was a dead link. I don't know where to go from here.

I honestly don't know, because my old H&M file is installed in my system, but when i try to uninstall it says "missing files" though my UC works fine anyway.
I have had this problem with several other programs too. Sometimes viruses attached themselves to those files, and then of cause the antivirusprogram deletes the certain file >_>
It might be something in that case, and the only way to fix it is rebooting the system back to the original :/
So i just gave up on that

There's also a program call Revo Uninstaller that forces programs to uninstall: https://www.revouninstaller.com/rev...e_download.html
Never used it, I just found the link via Google on a question about uninstalling NL.

I did find an explanation for why you couldn't uninstall your game:
"Because the Add/Remove program function will just redirect to the Sims 2 folder unistallation. If the Sims 2 folder uninstall program won't work, then the Add/Remove program won't work too."

Thank you so much! That revo unistaller worked wonderfully!
