What operating system are you running exactly?

Yes there is:

<https://community.openvpn.net/openvpn/wiki/ManagingWindowsTAPDrivers>

In particular check C:\Windows\inf\setupapi.dev.log. It contains
installation logs for Windows drivers in general, not just tap-windows6.
It generally gives a pretty good idea of the problem. It should not have
any sensitive information in it so you can post the relevant lines here.
