As to your first reply, yes, I did all that and reinstalled. Still could not install RV and got the "latest update" error message again. Odd, because it installed yesterday even if it was only briefly.
I've uninstalled it again, cleaned up the computer, yet again and now I'm reinstalling...again. It takes almost an hour.
I have Ambitions, Generations, Pets, and Seasons.
I would assume that with reloading from Steam that I'd have all the updated versions, but I could be wrong. 1.67.... is their latest updated version. 1.69... is Origins. But that shouldn't be the issue because it played fine on my old system.
I still haven't had any response to my post on the Steam boards. Maybe I'll post to Carl's again to see if anyone has any more current information. I can't believe I'm investing so much time to this.

Riverview is my favorite town. I've done a lot of work there and I really want to be able to play it on this computer.

However, I will look at that patch link. Thanks.
