Cannot load Calibre App
Windows 11. Never had this issue before. I click on the installed app and..... nothing happens. No processes loaded. Have tried older install and still the same. Paused anti Virus etc. I've had Calibre since version 1 and never been faced with this.

Any ideas for trouble shooting?

I believe a recent windows 11 update blocks windows installer unless you are running with administrator rights.
A big PITA in my view.
