Keep getting same error "an error occurred installing the TAP-Win32 device driver" tried installing various OpenVPN installer packages, using Vista SP1 compatibility and and Admin privileges set. Tried changing driver signing requirement too, and still doesn't install. SOME Windows 7 machines installed fine, while others (same model HP laptop) won't install the Tap device driver. I've searched ALL the forums and can't find a solution.

Hope this helps http://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/566ffaf9-7225-465a-a626-d5aac02cfb5b/
