To work, it was necessary for me to do this:
1) Updated Java and uninstalled old Java from Java.com using IE
2) R-clicked shortcut, selected Properties, under Compatibility changed Compatibility Mode to Windows XP and Privilege Level to run as administrator (despite being one already)
3) Clicked Yes on User Account Control
4) Clicked on Pie Diagram
The program opened and I was able to follow the Registration instructions.
Faster and more options than the similar free programs I’ve tried in the past, and I was interested in the $5 upgrade to Pro which has more options, but I couldn’t find any indication of how long the license was for.
