I previously installed VTUnes on my old system, now I would like to shift the program to my new system. Do I just simply uninstall VTunes on the old system and then reinstall it? Will there be any license issue?
Are you referring to the Single User License ? (I see that you have a single user license registered for VTune Performance Analyzer for Windows*) If so, you can install and use it on any number of machines, as long as you are the only user using it. There is no need to Uninstall.
