Thank you for the clarification.

I'd tried that several times, before posting.

After some time with Google, I found a thread, Another connection
problem', on the RPCEmu mailing list, from a couple of years ago, in
which David Feugey noted the same error messages. The solution then, as
now, was to downgrade OpenVPN to version 2.1.3, which creates Tap-win32
version 9.7.0. This is compatible with Win 7 Pro, whereas at least one
later version seems not to be.

Having changed the TAP driver, the errors have gone, and all is well.

Many thanks for your response.

Tony
