Hi! I was uninstalling some stuff on my computer, and when I was done I went to play The Sims 3. I uninstalled My Sims and The Sims 2, which weren't linked with my Origin account. So, I opened up the Sims and it told me to reinstall Origin, but Origin was already installed. I then opened Origin and it told me that The Sims 3 was not installed. Origin is giving me the offer to reinstall TS3, but I don't know if I should. What should I do?
Also, I do not have any anti-virus software running in the background.

Perhaps you already had Sims installed via a disc, and not via Origin - it is possible that Origin doesn't automatically detect your current installation path. You can set this yourself via Origin -> Application Settings.
It also wouldn't hurt to simply reinstall via Origin.

Hi! did you get this fixed? My macbook pro is giving me the same error and I can't figure out why.
