Okay, I took this approach, and now have a working OpenVPN installation
on that system.
I started out by running the TAP-Windows -> "Delete ALL TAP virtual
ethernet adapters" option of the Windows Start Menu.
Then, since I already knew from looking through the setupapi.dev.log
file and the output of "pnputil" that the tap0901 driver was called
"oem43" on that system, I just went ahead and deleted the driver
directly (based on what the Remove-Tapwindows.ps1 script would have
done):
====
C:\WINDOWS\system32>c:\windows\system32\pnputil /delete-driver oem43.inf
Microsoft PnP Utility
Driver package deleted successfully.
====
In hindsite it looks like running the "add adapter" script would have
done this automatically, but I went ahead and put the Win10 version of
the driver back in the driver store by right-clicking on "C:\Program
Files\TAP-Windows\driver\OemVista.inf" and choosing "Install" (since I
new that that the files in that directory were indeed the Win10
versions)..
And finally I added the virtual adapter back in by clicking on the
TAP-Windows -> "Add a new TAP virtual Ethernet adapter" Start Menu
entry.
At that point, the "TAP-Windows Provider V9" device showed up again in
Device Manager with no warning triangle in the icon, and when I clicked
on the OpenVPN icon it proceeded to start the VPN connection without any
trouble. So I think the situation is resolved on this machine.
Given that we now have the correct driver files installed I am no longer
able to do much testing related to the installer being confused by
having the wrong ones in use... but I have kept copies of the various
setupapi* log files, so let me know if I can provide any additional
information....
