I have used Stardock for years throughout all of it's software evolutions.
About a year ago I did a fresh install of Windows 10 and installed DS10. No matter whether it is new downloads or old stored dreams using videos, Dreams, or Windows Backgrounds, when I tell it to apply the background, The background turns black and DS just sits and spins. I can generally kill it via the Task Manager. I have now purged it, upgraded to Win 11 and DS 11, and STILL have the same problem. DS is one of my favorite tools and I have been unable to use it for over a year now. I am running two 1080GTX TI in SLI mode. Up to date Nvidia drivers, and no clue. Any ideas to try? Nothing is reported in the Event Viewer. The Deskscapes config app lists as 32 bit and has two processes running, with the 2nd one Not Responding forever. Nothing else on the PC seems impacted.
