Unable to create virtual adapter from CMD in Windows x64

Post by renjithkathirolil » Tue Feb 06, 2018 3:52 pm

Hi,

I'm in the process of creating a VPN app for windows using softether.

I'm able to start vpnclient service but I'm unable to create virtual adapter using the following code :
SoftEtherVPNClient\vpncmd_x64 localhost /CLIENT /CMD NicCreate VPN

The commands are run as administrator and the following errors are returned:

VPN Client>NicCreate VPN
NicCreate command - Create New Virtual Network Adapter
Error occurred. (Error code: 31)
Installation of the Virtual Network Adapter device driver failed.

If VPNClientManager is running, the above error is not shown and adapter will be created.
Is there any other way to create virtual adapter without running the VPNClientManager?
