OpenVPN and Windows Seven

I may be unlucky but the only way to make openvpn work with Windows Seven was that way :

• Make sure to install the last version (that is at least 2.2.1)
• right click on your openvpn-gui-1.0.3.exe file
• select properties
• select tab compatibility and set it to Windows Vista Sp2
• click the checkbox run as administrator
• It should work
