A previously installed Reader (that comes pre-installed, I didn't do it and Creative Cloud didn't do it) blocks the installation of the licensed Pro, with no explanation to the user. Only by dredging through online chaff does one eventually find this explained by a helpful volunteer. It is a truly remarkable piece of engineering and customer support on Adobe's part.
Hi @charlesc56982430,
Hope you are doing well. Sorry for your experience!
This looks like Acrobat Reader was installed with the OS installation.
The installer for Acrobat on the Creative Cloud Desktop App installs the basic version of Acrobat, and it requires additional install of premium features from within the app.
What I suggest would be to install from here: Download Acrobat installer for Enterprise term or VIP license (https://adobe.ly/3TVvzNm)
