I just had to sign up in order to reply to this particular thread.
I used to work for Microsoft as part of the Vista team before Vista was released, Hell before RTM was released.
You can't install it because you don't have Ultimate. It only works on Ultimate. This likely won't change because as I said, it's Microsoft's way of getting people to buy Ultimate in the first place. If Stardock somehow made Deskscapes work on other versions (which isn't possible because the technology needed is only in Ultimate) it would likely violate the partnership and Microsoft would not be happy with that.

The part in the quoted section that is inaccurate is the technology needed is only in Ultimate. The technology in Vista is the same regardless of the version. I hear this crap all the time oh how Ultimate is different from home premium and home premium is different from basic, they are entirely different systems.
Every version of Vista can be installed from any Vista disc. If you are installingt Vista yourself and NOT running a recovery from an OEM disc like from HP or Dell, then it will come to a point asking you to enter your serial number or to tell it which version to install. That serial number or your choice determines which version. So what exactly is the difference? Not much. It doesn't actually install a different version. It installs the appropriate graphics for ultimate(splash screens), it turns certain options on and off, and sets Ultimate only flags. The only installed differences are a few behind the scenes applications, and library extensions. Microsoft is so sure that this is rock solid, that ANYHTING that will "only" run on a certain version, it will just check the flags, if certqain things are turned on and if the flag is set as the version it needs.
It is a trivial matter if you have Vista Home Basic, to go in an turn on the Windows Aero Glass interface, which supposedly the technology only exists in home premium and ultimate. However if you switch on the right flags, you can enable it. It's already installed. There are just 2 flags, and 2 services that are not allowed to turn on. The technology is there and it is installed. Vista is Vista. The technology is alal identical. The idea behind dreamscenes and the like is nothing new anyway. You'vebeen able to do this since XP. Just download and install a couple f DLL files, and do some registry editing and bingo, you cfan use any number of video files for a desktop background.
So please please stop spreading the ignorance that the technology in different versions of Vista are different. The only difference in each version is nothing more then some system flags being turned on and off.
