Fortinet VPN Client 5.4- Windows 10 Creators Update - 98% - Connects/Disconnects

Since upgrading my Windows 10 laptop to the latest creators update, the fortinet client no longer connects to the server.

I get to 98% then it fails.

Some of the errors I get are,

Has any seen such an issue, or know a fix?

Thanks,
