Hey guys,
This is really frustrating. I spent way too much time trying to figure out on my own, and I decided that if you guys can help me, it would be so much better.
I downloaded the base game, and it worked fine. I tried downloading an EP (Ambitions), it would download, then when I try to start up, it says "Unknown Error Occurred."
I tried to uninstall, and it says "You can’t open the application “The Sims™ 3 Uninstaller” because it may be damaged or incomplete."
I went through every step that BluebellFloraBluebellFlora has wrote about regarding going through files and deleting them. Then I tried the manual super patch, and the launcher worked again (the base game only). Then when I tried to download an EP, it would say "Unknown Error Occurred" again.
I am running on MacOs Sierra (v. 10.12.2) and I have a MacBook Pro 13-inch with Retina Display. The processor is 2.7 GHz Intel Core i5.
ANY TIPS WILL BE HELPFUL, I AM TRYING TO GET BACK TO THE WONDERFUL GAME OF SIMS 3
HAY so I was wondering if you found a solution to this issue?? I've been experiencing the same problems with the same laptop set up as you, and I think I've found a bit of help for you.
I uninstalled/reinstalled all of the expansion packs I have so many times only to have the "unknown error" occur again I started a process of: download/install base game, update it, try and get it to launch, just to triple check that it would be okay. If it worked, I moved onto an EP and did the same process until I found the EP (in my case it was Late Night) that caused the "unknown error," After hypothesizing that it was Late Night causing my issues, I did a final clean uninstall of everything Sims 3, and then reinstalled and updated each EP using the same method as before, just excluding Late Night.
It worked for me!! I have all my EP's and SP's cleanly and beautifully running on my laptop, save Late Night and can finally get back to playing. Hopefully maybe this was a bit helpful to you if you still need it?
This also leads me to a question of my own I have now...what the heck is wrong with my Late Night expansion? I really don't want to risk trying to install it and have to start fresh all over again, but I also miss its features. I've done this all through Origin, not using any of the discs. Anyone have advice? Looked around for someone with a similar problem (one single EP seeming to cause them trouble) but didn't find much help.
