FortiClient stucked at 70% (Windows 10 Preview version)

Dear all:

My Firewall is FortiGate 80C, I have been setup SSL VPN and using Android phone, MacBook Pro and Windows 10 notebook connect to my FortiGate working well for 3 years.

But I upgrade my Win 10 notebook to "Insider Preview version" around 10 days ago then my FortiClient can't connecting successful anymore. (Build 17046.rs_prerelease.171118-1403) It always stucked at 70%...

Would you please help me to figure out what is wrong with it?

Should I have to wait FortiClient upgrade by FortiNet to fit the new version of Windows 10?

Thanks for your helping, thanks!
