How can a program determine what version of Adobe Acrobat/Reader DC installed is 32-bit or 64-bit?

On Windows platform, I can look at the title to see if (32-bit) or (64-bit) in the title from Adobe Acrobat DC or Reader DC 2021.

I am looking for a way to allow a custom install program to determine if the installed of Adobe Acrobat or Reader DC 2021 is 32-bit or 64-bit, is there some registry or something from Adobe Acrobat set after installed to indicate this?

If the Acrobat title with the text 32-bit or 64-bit is stored in some registry or somewhere in the file system then the custom install program can also get and parse the title for the text string to determine 32-bit or 64-bit. 

Thank you.
