Certificate Error when connection from a certain client

Hello Forum :) I have a problem with a Forticlient doing an ssl vpn to a fortinet after a firewall update to 5.6.3

The client also updated to the latest fortclient. Now, when trying an ssl connection, it stops after 40% with error (translated from german...) : The server needs an authentication, please choose a certificate (-5).

This happens only on one client and is not a user problem. The user login works on other workstation, also other user credentials on this client have the same problems. I tried then also to do a ssl vpn connection to a fortinet from another customer, same problem. It stucks after 40% with same error. So I think a client problem. Do you have any idea for me, what I can do? I will not reinstall Windows 7 Client. Thx in advance
