I have spent a days trying to find a workaround without success.I haven't found anything on the Adobe website that addresses the problem for any program. Even with all the alterations I can not deploy the updates. I fixed that by adjusting the registry by putting. I can not install the updates (.msp programs) to Acrobat Pro 8.0. Acrobat Pro then became a known program ('huh?) but still was not on the drop down list. I partially fixed the change by removing Acrobat Reader. After the upgrade, the primary Acrobat program was changed to Adobe Reader DC and Acrobat Pro 8 was relegated to an 'unknown program' and dropped off the drop down menu of choices for a default program menu. It was working just fine in Win 7 (updates and all). My primary Adobe Acrobat program is Acrobat Pro 8. Well, in my case that is only partially true. I believed the hipe that Windows 7 programs would run on Windows 10. Problem: I upgraded one of my computers from Windows 7 Pro to Windows 10 Pro.
