Adobe Acrobat 9Pro removed by Windows 10 update

Adobe Acrobat 9Pro and Adobe Acrobat reader both of which wer working perfactly just vanished (uninstalled) after todays Windows 10 updatation. My current Windows 10 OS Build is 19042.1415.

I had to reinstall Adobe Acrobat DC 64 bit version 21.007.20099. to get the Reader fuctional.

I checked in the Control Panel> Programs and Features to check if Acrobat 9 Pro application still exists and find it totally gone.

If I try to reinstall  Adobe Acrobat 9Pro from Original location, I get en error "You already have a better application with more features... etc the Installation will terminate here"" and the installation does not allow me to reinstall.

I have Adobe Acrobat DC 64 bit version 21.007.20099.

My guess Windows update unstalled this application, is it true ?

Is the current version of  Adobe Acrobat DC 64 bit version 21.007.20099. really more features than Adobe Acrobat 9Pro ?

Thanks
