I recently purchased a laptop with Windows 11 Pro. I was very surprised that my QB Pro v. 2019 works! I installed it from my original installation CD without any problems and it really works. I was able to open all my QB files. Of course, the installation disk doesnt have the recent updates including the important 1099  -NEC update. I had read in many places that QB Pro before 2021 would not work on windows 11, but apparently this isnt the case. Any thoughts?
