OpenVPN & Windows 7
There’s a great GUI out for OpenVPN & Windows, located here.
However, this GUI includes an old OpenVPN, that is no longer compatible with Windows 7 and Windows Vista.
The TUN/TAP driver will be blocked due to compatibility issues, and when trying to connect to a VPN, you’ll get an error along the lines of:
All TAP-Win32 adapters on this system are currently in use
The simplest fix, is to install the GUI package (including the old OpenVPN binaries), and reinstall OpenVPN afterwards.
