Maximizer 11 is not supported on Windows 10 so it's a little difficult to make a recommendation with any authority.
However I would say that a couple of times this week we have come across problems with Maximizer (later versions than 11) not opening. Both seemed to be related to a Windows update.
Uninstalling and reinstalling resolved the problem in these instances.
As I say, this is not a recommendation, but MAY be information that you find useful.
Do with it what you will. We have no experience of installing Maximizer 11 on Windows 10.
