With Pro7, Renewed Vision changed the way they do licensing (for churches, at least).
With Pro6, you could have it installed on any number of computers (with the same operating system, so either Mac OR PC, and changing that required an additional fee). You could only PRESENT with one at a time though.
With Pro7, they dropped the single OS requirement, but you have to unregister and reregister computers as you use them.
So, is that a big deal? How long does it take? Watch the video above to find out.
