Windows 7 Pro SP1 64bit laptops - I've had just a couple of laptops that I can't install the client on. I'm using the ForticlientOnlineInstaller. Windows throws the msg, and I have to rollback the install.
I've used gpedit.msc - User Configuration - Admin Templates - System - Driver Installation - Code signing for device drivers - Enabled - Ignore - reboot - to tell Windows to ignore the unsigned driver. But still no luck, same msg from Windows.
Is there a difference between the FortiClientSetup_5.4.0.0780_x64.zip client and the OnlineInstaller.exe?
And does anyone have a fix for this issue? I doubt that I'm first one down this road.
It could be something within Windows on those particular laptops.
