Anyconnect fails to connect with a message that it tried to set a specific MTU but it was already enabled with a different MTU - (SOLVED)

Cisco Anyconnect 3.1.05160 fails to setup the VPN tunnel, it prompts with this message:

"The VPN client driver encountered an error. Please restart your computer or device, then try again."

Authentication and everything seems to go through but it won't work.
The computer is a brand new HP with Windows 7. I have treid first with some later 2.x Anyconnect with same result.

The follow entries are printed in the event log:

This was caused by the good

This was caused by the good old HP mess-up-your-computer services. 

Disable the service "HP Device Locking / Auditing" and the VPN will be able to connect.

Disabling the HP Device

Disabling the HP Device Locking / Auditing fixed the problem for me.
