Purchased 3 times for three systems but can't install
I'm having trouble with registering Start 11 for this pc. This happens when reinstalling Windows and reinstalling Start 11. The dialog box says it's unable to install because it's active on another system. I've purchased one copy for each system and all three have come up with the same message. I've already had to uninstall and reinstall several times to get the other two working. How to fix this?
