I found this on moddb
Which also has me concerned if I do get SW:RC, cause I have vista as well.
Perhaps a SandCrawler Mod update for windows vista might be in order?
"I have a computer that runs Vista Ultimate and I need to install the stuff into Program files (x86). When I click on "Sandcrawler Mod v.1" it says that a problem caused it to close. i already installed the Apprentice maps to Program files (x86). Help please!!!!! "

I'll have to do some checking, but I though the apprentise maps, and a sandcrawler mod both ran and installed the same way. Otherwise I need somebody with Vista to test for me, it will be a good time to add some more maps, and add all the maps to the map loading screen, and the map list.
