Yes, it can be used on Windows 7
The problem is :
The route ADD commands in open VPN gui doesn't get executed, even if you run open vpn GUI in administrator mode.
Solution:
1. Go to C:\Windows\System 32
2. Run cmd.exe in administrator mode (right click on it and select Run as Administrator)
3. Copy all the failed route ADD commands in open VPN gui and run it in this DOS window.
Code:
route ADD xxx.xxx.xxx.xxx MASK 255.255.255.xxx xxx.xxx.xxx.xxx
4. It should show OK! for all the commands if successful.
5. Reconnect using open VPN gui, there would be no route ADD errors this time.
6. Connect to the machine you want using RDC / putty or any software you wish.
You are done.
