I'm going to counter that Schip by saying I had 3 copies of Riverview installed on the Vista PC before my last uninstall/reinstall brought it to my attention and I deleted two copies. During the time I had the 3 copies, I only had one show up under "Select a Town". Simstar, I found my multiple copies in the launcher under Installs labeled Riverview, Riverview1, and Riverview2 (I uninstalled them from here and deleted them under Downloads). I'm pretty sure they also showed up in my Downloads folder under Documents/Electronic Arts/Sims 3 (I deleted them from here too).
