That doesn't make a difference either. I have XP running on a machine with an nVidia high end SLI configuration, 4 gigs, yadda yadda yadda, nothing will make Deskscapes work on my machine, it'll even sometimes cause the whole shebang to crash outright. I was however able to get 2 of the backgrounds to work in the trial version, but as soon as I forked over the money for the full version those stopped working too. I think the program is simply buggy as hell and shouldn't have been released to the public. I intend to dispute the paypal charge and demand my money back for this. Shame too because I'd have really liked it if it'd worked. Should have just stayed with the free one.
