Thanks for posting.

Any info on the root cause of why this happens?

In my case faced this problem on Win8, due to the TEST CERTIFICATE not installed in proper store. In that case SEP installation will succeed but 'Firewall driver is not loaded'.

But this solution resolves when SEP has 'Firewall driver is not loaded' issue.

nevermind.....after much toil, i was able to uninstall SEP which automatically fixed the network issue and reinstalling fixed the original issue (i.e. firewall driver not loaded message).
