Net Activity Diagram 2.5 SR1 Setup (window)
Another user is running Net Activity Diagram.
You need to quit all Net Activity Diagram instances and run the installation again.
NAD is not previously installed. Why is this happening. Is it because I have it installed on my XP machine and the license is only for one PC?
I have the very same problem, is there anything I can do to run NAD on my W7 machine?
