Manually un-installing Sims 3


I was trying to do a fresh install of Sims 3 on my sisters laptop earlier but after un-installing World Adventures the computer still thought it was installed. Because of this whenever I tried to start the installer it automatically decided to try un-installing World Adventures again! After asking around for help I discovered that there were instructions for manually un-installing your games. It turns out that my problem was the un-installer was removing the program but not removing the un-installer file once it had finished. Hopefully EA have fixed this now, it can’t be that difficult to get the un-installer to delete itself when it is finished! I thought I would post the information I found here, partly as a reference for myself, but also as I hope it will help anyone else who runs into this annoying problem!

Sorry in advance for the essay length of this post! All the information here is taken from EA support pages apart from Outdoor Living which I  found on the forums (as there doesn’t seem to be a manual removal help page for that yet!) Please be careful when following these tutorials, they are pretty simple but even the easiest of things can go wrong so when it tells you to back things up you might want to listen!!
