Error during installation of windows client OpenVPN 2.6.1 amd64 OpenVPNMSICA tap_create_adapter Error 536870397 solution

Hello, the approach seen at https://forums.openvpn.net/viewtopic.php?t=31235&sid=d7084fe88d298938ee12e8e60ebfb2a0 simply doesn't work. Could someone please help? I have grown less confident in the OpenVPN technology, not to mention it's said to be already blocked in China. Many thanks.

What worked for me was choosing Customise during installation and disabling the Drivers option.

Thanks. So do you have to subsequently install the drivers from somewhere else again? I can't fathom how they were installed in the first place.
