Thanks!  After I installed/uninstalled twice, it was still still not working.  I used both the Windows 10 uninstall feature and the Proseries uninstall.  Finally I went into my C drive and deleted the ProWin19 directory (after backing up 19Data folder.)  The uninstall was leaving folders inside the ProWin folder that was preventing the software from working correctly.  After downloading program from Proseries a third time, it worked.  Thank you.  I was not about to call support unless I absolutely had to do so.
