Adobe Acrobat PRO 64-bit for MacOS Catalina please..

[FranSalud]

Problem solved, conflicting with older versions that were still on the system.

[Dave Merchant]

Catalina works with Acrobat DC, Acrobat 2017 and Acrobat 2015. Anything prior to that is off the table.

If you have a subscription then you should be using the latest Acrobat DC version, not Acrobat X (which hit end-of-support four years ago).

Don't understand your question. There has been a 64 bit version available for about four years.
