I deleted my Sims 3 Icon and it's place in my computers folders because I thought that meant it would uninstall it? But not I want to reinstall it and whenever I put in the DVD "Unable to Start Game, Error Code 317" pops up. How do I fully uninstall Sims 3 and reinstall it? I got rid of EA Download Manager also but I have Origin now.
Try a clean reinstall following the instructions here: http://simswiki.info/wiki.php?title=Game_Help:TS3_Uninstall and here: http://answers.ea.com/t5/The-Sims-3/Help-Guide-All-in-one-fix-except-hardware-issues-PC-only/m-p/734... where it says Delete game installers
Manually delete everything if above method does not work: https://help.ea.com/article/manually-uninstalling-the-sims-3
Make sure everything Sims is gone from your computer before reinstalling
If the game still shows in your Uninstaller Menu afterwards, you can use CCleaner to get rid of those.
