Installation Failed: Adobe Acrobat Reader

Hello,

I'm trying to install Adobe Acrobat Reader (free version) on my Macbook Pro running Catalina 10.15.7.

Whenever I get nearly to the end of the installation process, I receive the following error:  "The Installation Failed.  The installer encountered an error that caused the installation to fail.  Contact the software manufacturer for assistance."

I have already tried most of the basic recommended trouble-shooting.  I previously had Adobe Acrobat Pro on my computer, which I fully uninstalled.  I deleted all previous install packages and emptied the trash.  I rebooted the computer.  I also tried to install Adobe Acrobat Pro DC, which also failed with an 136 Error Code.

I specifically need Adobe Acrobat Reader to follow precise instructions from my book publisher for editing manuscripts, and the work is due in a few days.  I would be so grateful for some assistance.
