AnyConnect Client v3.1 driver error on windows 7

[Alex Hwang]

Hello,

I used AnyConnect Client v3.0 on my windows 7 machine and worked well. But after automatic upgrade to v3.1 by the VPN server(ASA) and it does not work any more. It seems that VPN authentication is successful but activation of VPN adapter fails.

I see two error messages below:

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

AnyConnect was not able to establish a connection to the specified secure gateway. Please try connecting again.

I already did most of suggestions below from google but still the issue has not been resolved.

- Rebooted the laptop

- Confirm ICS disabled

- Remove Anyconnect client from the laptop and reinstall

Hi Jeong,

Can you colect the DART logs and send it across?

Thanks

Hi Shetty,

Thanks for the response. I've attached the DART logs from DART ver 2.5.6005.

Many Thanks

Hi All,

The issue has been resolved after I installed a newer version of Cisco Anyconnect 3.1.04066 from the ISO image and VPN connections was established. Looks like something wrong with the Anyconnect Client installed via the VPN server (ASA5500).

Thanks

Jeong

Dear Jeong,

I have the same trouble with you, but I can't get the Cisco Anyconnect 3.1.04066. Could you send the ISO image to me? I'll be very grateful for that!!

Thanks

Hi Bresdifet,

The image attached. Good luck for your troubleshooting.

Dear Jeong,

Thanks very much! Before you attached the file I had uninstalled all of the network card driver, then reinstalled it but all of them was Yellow Excalmatory Mark. So I can't connect internet now, oh my god!

I am also facing the exact same issue. I even tried with the newer version. But it does not work. During connection, it asks for accepting the banner and the suddenly the cisco adapter driver gets uninstalled from device manager and cisco pops-up the error screen.

" the VPN client driver encountered an error. Please restart your computer or device and try again"

Please help.
