My computer froze on me while in the middle of working on a return.  When I rebooted the computer it told me the program file was corrupted.  I uninstalled and tried to reinstall pro-series and now I am told I need to have win 10 64 bit installed.  I am in fact running win 10 64 bit.  I seem to recall I had this issue when I originally installed 2019 before tax season.

Can't remember how this was resolved.
