I'm enjoying my purchased RDM, however, I'm moving onto a new position. I'd like to somehow "de-register" my current machine and be able to use another machine. Is there a process already in place for this?
You could delete the remotedesktopmanager.cfg file in %LocalAppData%\Devolutions\RemoteDesktopManager.
Register the application with the same name and serial number on the other machine and you will be good to go.
