Re: Sims 3 Uninstallation Issues

@Ko0me  The registry entries do in fact contain the product keys for your packs, and if you haven't deleted those entries (or you do a system restore), you can find them easily enough:

As long as your packs are registered in Origin though, you should be okay, whether or not Origin thinks you also need to buy Access again to play the game.  The only other reason you'd need the keys is if you plan on reinstalling using your disks some day and have lost the case inserts that had the keys printed on the back.

I don't know what's on your hard drive, but yes, it sounds like deleting the files in the Electronic Arts folder (we're talking about the one in program files, not in Documents, right?) should remove almost all the data taking up space on your hard drive.  This doesn't touch the registry, but the stranded entries don't matter unless you later reinstall the game.

For Revo, I've only tried uninstalling Sims 3 with it once, and that was almost a year ago.  But these are the notes I took at the time:

• launch Revo
• highlight a pack on the list
• click Uninstall up top
• after uninstall, select Moderate under scanning modes, and Scan button
• when it says found leftover registry entries, click select all, then delete
• click next
• when it says found leftover files and folders, select all, then delete

Sorry they're not super detailed, but I was just messing around a bit to see whether it would work well enough to recommend.
