Hello everyone !

I have searched on the internet and in the differents guides but no solution until now...

Any solution to suggest to me ?

Thank you already !

Have you heard anything yet? I have an entire department of engineering laptops that we are upgrading from windows 7 to 10 and none of them will connect to vpn after upgrade?

Hello,

For the moment I still don't have any solution...

Maybe the best would be to downgrade the computers ?

VPN, CISCO AnyConnect, Failed to load preferences error message

When attempting to open the VPN client, the following error messages may result: "Failed to load preferences," or "The VPN client failed to launch the client user interface application."

It appears that there may be corrupt preference files.  If there is more than one user account on the computer, it is suggested to remove the files for each user account.

My solution is a bit wonked, but it has worked on multiple Win 7 and 10 computers with the interface stopped working error. This is on a corporate, domained network.

Fire up mmc with admin, start the Certificates snap-in, computer account, local computer, expand certificates, expand personal, click on certificates.  I had pages and pages of p2p certificates, most dated in the past.  There should be a minimum of one PC cert in our org, so I deleted all but the corporate-issued PC cert, Cisco started working again.
