The issue is that C:\Users\All Users is a link pointing to nothing, and doesn't exist. Same for C:\Documents and Settings. It's a link that points to nothing.
In fact, the links somehow link to S: instead of C:... Go figure how I managed to wreck that? I think making myself instead of Trusted User the owner of the C: drive may not have helped. Anyhow, a little bit of cygwin/ls -l/rm/ln and I've been able to locate the damn file, which is in C:/ProgramData (to which All Userss is an alias)...
Finally, the zip (I hope it's the good one...). I hope the dl time isn't going to be as awful as the upload was, but I've got poor upload times, so I hope stardock can get it.
