Acrobat 2015 Installer (Acrobat Professional Version 12.) crashes on macOS Catalina 10.15.7

[Béla5DB8]

After clicking 'Continue' in the step 'Introduction' the Installer-Programm switches to the step 'Read me' and at the same time the mouse cursor switches to the 'Spinning Wait Cursor' which revolves and revolves and revolves.... and at the same time the Installer-Programm crashes (The 'Force Quit Application'-Window in the macOS-Finder shows, that the installer is 'not responding'). 

Language of macOS and Acrobat: German.

How can  I solve this problem?

You can't solve it. This version of Acrobat is not compatible with Catalina.

Thanks for the answer and link which does explicitly mention "Pre-August 2019 versions of Acrobat DC, Acrobat 2017, and Acrobat 2015 applications cannot be licensed on macOS 10.15 Catalina and later versions...".

But what confuses me is that according to Acrobat and macOS 10.15 Catalina compatibility :

"Acrobat DC, Acrobat 2020, Acrobat 2017, and Acrobat 2015 are compatible with the new macOS 10.15 Catalina."

?????

Catalina needs all new apps (2019 or later). Throw your old apps away, it's part of the Joy of Mac.
