I've problem with FortiClient v6.0.9.0277 on Windows 7

I've installed FortiClient v6.0.9.0277 on my Windows 7 to connect a network at my work place office.

But after connecting to the VPN I've this error message:

--------------------------- Warning --------------------------- Failed to establish the VPN connection. This may be caused by a mismatch in the TLS version. Please check the TLS version settings in the Advanced of the Internet options. (-5029) --------------------------- OK    ---------------------------

I've changed all TLS version in Internet Options, but after each changes I've this warning again ...

Thank yout
