What I meant about Vista security is that I don't have ownership of the folder or any access permission so if I try to view the contents or open or move or delete the folder I get an access denied error. OTMoveIt was getting the same since it's effectively running as me, it didn't have permission to do anything to that folder. By taking ownership I can give myself full control and OTMoveIt should then have no access problems. OTMoveIt seemed to kill and delete the service ok so it should hopefully just be a dead file.
Sorry I know this is your field, I'm an IT consultant so I can't really help trying to think of solutions myself
I am just trying to remember when I ran OTMoveIT I launched it as Administrator by right click, run as... but I didn't actually set the .exe to always run as admin, so when it rebooted it probably ran as me.
