Just check Windows Ultimate Extras under Windows Update for Windows Dreamscene or look for Windows Dreamscene in the installed updates, confirm that you've installed the update.

You should then try uninstalling and then re-installing deskscapes and .dreams should run fine.

well i was able to get it working I found the dream files in my documents stardock folder and double click them they run but still no control dialogs or anything available... wish there was a help file or something.

DeskScapes supports nearly all versions of Windows including Vista 32-bit, Vista 64-bit  (Home Basic/Premium/Business/Enterprise) and 32-bit versions of Windows XP.

Its just that Vista Ultimate users can download full version of deskscapes 1.02  whereas others mentioned above have to purchase deskscapes 2 to get the full version or else they can just play 5 dreams included in the free trial.

Just right click on your desktop, select Personalize, then Desktop background, in the drop down click on DeskScapes animated wallpapers or simply browse to My Documents/ Stardock/ Dreams from here and it will show you the thumbnails of all dreams, select the one you want, below that select how it should be positioned.

Hope this will help you.
