It will begin to install then stop when its on sunsetvalley.objectcache and have an error message what can I do?
When it repeatedly stops on the same spot, then there is something that needs to be done. Sometimes that means that you have something already there (like an incomplete uninstall). Sometimes it means that there is a problem with the computer (not as likely). If you're installing from a new disc that you've never used before, it can be that there is something wrong with the disc itself. (I had that problem with Sims Medieval. They recommended that I take the disc back and get a different one. Unfortunately, mine was a gift, so I had no where to take it back to. So they gave me a direct download instead. I don't like having downloads, but it's better than no game!) If it isn't an incomplete uninstall, then you should contact customer service.
