Just a thought. We know that people have problems with the Prevx licensing system. Deactivating 1 licence usually works - assuming that the user has set up MyPrevx - however 2 or more license changes at the same time will usually fail in the console. I've been recently installing & using Backup Assist, a good reliable server based backup utility. Backup Assist has a licence system where you can deactivate the licence from the current computer from within the software. You can then install & activate the software on another box. An idea for Prevx?
