Fresh Install OCR Errors

Hello, just installed Adobe Acrobat Pro 2020. Trying to OCR some text from pictures. I get an error message: "Unable to locate PaperCapture recognition service. Your installation may be corrupt."

No problem. I follow the Learn More button, and do what it says. Then I get "Acrobat could not perform Text Recognition on this page because:

Unknown error"

Super. So I uninstall, clear the Acrobat folders & reinstall, and get the same sets of errors (see attachments).

Now what?
