NOTE: FlushIpNetTable failed on interface [22] {88C21B16-3D85-4B9C-A65F-10F89A2DEACB} (status=5) : Access is denied.  
C:\WINDOWS\system32\route.exe ADD 208.111.39.186 MASK 255.255.255.255 192.168.11.1
ROUTE: route addition failed using CreateIpForwardEntry: Access is denied.   [status=5 if_index=11]
Route addition via IPAPI failed [adaptive]
Route addition fallback to route.exe
The requested operation requires elevation.

Firstly, you should run OpenVPN as Administrator:

Secondly, add the following to the client config file:

route-method exe
route-delay 2

Solution 2

The problem is the access denied on route.exe command. If you're using windows vista/7 then you must run openvpn with elevated privileges.

Solution 3

In fact, it is a problem with permissions, but that has been fixed.

I just updated to the latest version of OpenVPN for Windows (2.3.11 at time of writing) and now it works flawlessly.

OpenVPN can be downloaded here.

    I can no longer ping 10.8.0.1 and it appears as if my internet traffic is not passing through the vpn at all anymore. I had it setup to route all traffic over the vpn. Any ideas what might be going wrong? Thanks for any advice.

    P.S i am connected via wireless to a buffalo router but the vpn client is only my laptop and the openvpn server is pushing 8.8.8.8 to my laptop.

    Just setting run as admin worked for me on Win10 Home- I didn't have to edit the client config file. Thanks!
