Hi, sorry we have not carefully tested in terminal service mode. Could you please logon to the console and try from there? It should be very easy to uninstall it. You can either use Add/Remove Programs in control panel, or run the installer again to uninstall it.
I am sorry for your employee. DriveHQ FileManager software is very popular among business users / professional users. It is very safe and reliable. We have a huge number of companies using our software for group sharing and remote file backup.
