I want to create 2 separate tunnels on 2 separate subnets, so I have 2 separate .ovpn (client) files.

The 1st tunnel comes up, but the 2nd one fails because of a conflict over the same TAP-windows adapter. Evidently the 2nd tunnel needs its own TAP-windows adapter.

How to create a 2nd TAP-windows adapter? Apparently there used to be a utility packaged with the Windows OpenVPN installer - but there no longer is.

Answer 1

+1, I actually had to dig for this because the Add TAP Adapter link that used to be in the OpenVPN folder isn't there. This is because now it's a separate install (see this ticket), and as such the utilities are located in the %PROGRAMFILES%\Tap-Windows folder, under that folder there is a bin folder, and you can run the AddTap.bat script to add a new adapter, with elevated permissions of course.

Answer 2

There is already a driver for new installation at:

C:\Users\Luis->dir "%PROGRAMFILES%\TAP-Windows\driver\"
 Volume in drive C is Windows7
 Volume Serial Number is: 54AF-1483

 Directory of C:\Program Files\TAP-Windows\driver

You can simply install a new TAP adapter referring this path with the New Hardware Wizard at Control Panel (just running hdwwiz.exe on Win Vista and above). Select Manual Installation --> Network Adapter .

Tested on Windows XP SP3 and Windows 7 SP1.

Example of my Windows 7 SP1 computer with a physical NIC, 2 TAP adapters, a PPTP and a virtual NIC created by VirtualBox:
