uninstaller

@naebetmr You can uninstall using Origin or Windows. In Origin right-click the game panel and choose the Uninstall option. 

Alternately in Windows open the Control Panel the Programs & Features. Check for the game on the list, and choose to uninstall from the right-click menu.

A lot of programs don't come with specific uninstallers nowadays, so this is the generic removal process. 

Yes, there is! Right-click game folder inside Origin (tab My Games) and select uninstall or you can uninstall using Windows (under Programs and Features).

EDIT: Uhhh... two minutes late! EA_David got it first!

thank you for the answer. 

the thing is, that I got a refund for the game. And its no longer in "my origin" menu. But i still have it on the computer.. Any way to get rid of it ? 

I can't uninstall The Sims 3 (both the base game and expansions/stuff packs). Not by using the Origin "uninstall" option and not by the Control Panel... It glitches or something... Please help me! I really want to uninstall it, I don't play it anymore... Plus I really need the space since my computer is really slow and it's like 18GB of Sims........
