Sims 3 game won’t open Watch
To id your saved game? save that first. Move a copy somewhere else.
I think the icon wont work because a new one for your expansion will have been created and that took over? ie its not linked to the game anymore.
Cant you see it in your installed programs list?
1. Try and locate the new sims installation. If you are in windows 10 it should just be in file explorer. It will also be on your C drive under x86 program files or just program files. there should be an icon in the folder to click on.
2. If you have the saved game then you may be forced to just reinstall, but the saved game should work.
