Vizard provides a way to unregister a license and then provide you a way to get a new license. I've had to do this a few times moving my floating license server around.
From a command prompt on your computer, change to the bin directory under the location you've installed Vizard. From there type:
winviz UNREGISTER
Follow the instructions that come up, and when it's done, it should provide you a code to show you've unregistered Vizard.
Once you've installed Vizard on your new computer and have the new hardware code for it, take that and the unregister code and send this to
support@worldviz.com. The should send you a new license code for the new system.
I've had to move my floating server twice so far and haven't had any issues either time.
