Folks,
I have the exact same issue that's presented here, except that I'm trying automate Excel using a non-system (user) account. The solution of creating a desktop folder doesn't work, because the user already has a desktop folder. I can get the solution to work for the System Account just fine. I can also get it to work for the Administrator account, when logged-in. Is this in fact a Session 0/1 issue or is that still a red herring?
There seems to be no way to do this.
