VPN stuck 98% or Immediately Disconnects

[mlam]

Found a solution, thought I would share to save you the headache.

Our environment:

forticlient 5.2.3.0633

http://www.fortinet.com/resource_center/product_downloads.html

win7 pro 64bit

fortigate 240d

Uninstall and reinstall vpn client only, need to reboot

Open forticlient add a new connection, select "do not warn of invalid server cert"

Try to connect, if it fails at 98% or immediately disconnects, 

Open network connections, find "fortissl" > properties > general > configure 

select 64K digital, use old proprietary protocol channel 1, enable hardware compression

Retry your vpn connection, this worked for me.
