At times Windows 8.0, 8.1, and Windows 10 SSLVPN client stuck at 98%, irrespective of the Forti Client version being used.
This happens even with the latest forticlient.
1. Download the Wan Miniport repair tools. Repairing them and restarting would fix the issue.
2. Another alternate is to disable them from Device Manager, restart and try the Forticlient.
This works.
