I've been running Calibre Portable at work off of a thumb drive for quite a while. We recently updated our desktop at work and I couldn't any longer run executable files like Calibre Portable directly off the thumb drive as a non-Admin. So I copied the whole Calibre Portable folder off the thumb drive and pasted it into my AppData folder (actual path = C:\Users\[USER]\AppData\Roaming) and ran it from there. Worked great. But IT saw it and asked me nicely to remove it if I didn't really need it for work. I can get by fine with Calibre on my home PC, so I said "Sure." I deleted the file from my work PC and re-started, but the file is still there. Since we run a networked system, Control Panel on my machine doesn't see it as a Program that can be uninstalled. There's no Uninstall file in Calibre Portable that I could find. There were some registry keys that seemed to belong to Calibre and I removed them and re-started, but Calibre Portable folder still shows up.

I'd really like to solve this issue without further involving our IT staff. How can I keep this folder from re-installing?
