I just bought the demo of Mappoint 2004, North America. I will be using it on my laptop but until August I won't have access to the laptop. I want to familiarize myself with the program before actually taking off and using it. Is it legit to install it on my desk top for a couple of weeks, then when my laptop gets back, uninstall it from the desktop and install it on the laptop. The 60 day total limit from today is more than I will need. Do I call microsoft when I reinstall?
