I assume nothing. Did you take the steps necessary to apply Curtains? If you are using Windowblinds first you have to apply the the Default Microsoft theme. Then run Curtains. Did you do that?

Thanks for the reply yes done everything never used windows blinds on this pc and windows is set to the normal theme....

Main C Drive is a Kingston SA2000M81000G NVME 1TB

As for windows version here is a picture took directly from Winver.exe,

The program version is v1.18 Which when I Check for updates it tells me there are no updates. I Did install to the default directory too. And I Must state as can be seen the themes that come packaged with curtains work just fine using the Luma XP One now but it's when I Try to download new ones they download then go to installing but then just stop and I Open up the folders there's nothing in them. When downloading a theme from online it's the Curtains file double click to install and it just has an empty directory. Allot of the ones I Try to download in the program it's self just don't even try to download at all it's all very strange as you can guess I'm New to all this I Normally just use Ultra UX Theme patcher and use 3rd party themes but this program would and does seem to make life so much easier.

Thanks for the help guy's ! & Kind regards,

Pete.
