Thanks. NO, Mapping the drive does not work in relation to installing new Deskscapes items from within Deskscapes.
Can I map the drive letter and add it to the folder list, sure. But that is not the issue.
The issue is I cannot download and install a new Deskscape fom the "Online" tab inside of deskscapes. When I do, it proceeds to "Download" (Heaven knows where) the file. Then, instead of allowing me to Apply the deskscape, it shows me this:

Note: It shows me the path that the file should be located in, and gives me a new "Download this background" button, which does nothing, and the file is not in the location shown in the path. I have full privileges to the path. As far as getting with my IT people, I am the head of my IT people and we are all scratching our heads.
There is nowhere to modify where it thinks it should be downloading. So the only option I have is to go to http://dreams.stardock.com, search and find the dream I want, then open the file from there. If I do that, the file gets downloaded to "C:\ProgramData\Stardock\Deskscapes\ExtractedData" and I can at least run the dream, but it still does not copy the dream anywhere else.
