I know there is no official support for Windows 8 yet on the client software, pretty slow from Draytek but hey, need to get it working.
Client runs in compatibility mode but everytime the program starts it says The VPP driver <vppp.sys> is necessary for this feature! Please press OK to run the installation. It will run when you click OK but I was wondering if anyone knows a way to run the VPPP sys driver automatically or what needs to happen for it to work.

Hi, I had this issue, you can fix this by disabling driver signature enforcement, there is a guide here:
