11 has been a nightmare for me. I had a hair pulling experience when setting up Cantabile. Many Thanks to @Brad after several message exchanges, we got it going.
I went to 11 in February, only because 10 will end soon, and several developers are starting to require 11. 
I decided to install Omnispere 3 on my Win11 machine. I left Omnisphere 2 on my Win10 machine, as it runs very well.
As with everything involving Win11, it was a f**k up.
I had problems with Omnisphere dll. Win11 decided I needed a default file type association for the dll. I tried to bypass the default, but 11 forced me to make a decision before moving on. It forced notepad on me. Every dll I owned became a notepad default.
After hours reading, and trying Win fixes, it asked for a program that would host dll files. All it offered was Cantabile and notepad. I chose Cantabile. BUT, now all dll files are requiring only Cantabile.
I tried the app reset in settings and nothing changed.
I am stalled at this time.
Iāve spent several hours in Win forums and single hacks (which never work).
I am at the point of using some Reg edit hacks. As others were saying, Windows created this problem so users will be forced to only use Windows apps.
Regardless, every geek I know, has told me, 11is pure horse manure, and Windows now takes charge of everything. The users have no control. Linux is not quite ready for āprime timeā yet, but is looking good at this minute.
Mad as Hell,
Corky
