I created an account so I could post .
One problem is Avast AV has a problem with the 39.0.2234.0 update.
On mine it kept detecting a virus.
I believe this to be a false positive .
On my Windows 7 32-bit i had to rollback to version 39.0.2226.0 as posted above.
Disabling automatic updates with the work-around also posted above .
The VPN is now working this way .
On my Windows 7 64-bit on my laptop .
I had to exclude the problem folder in Avast .
Then 39.0.2234.0 worked .
The VPN works now on this OS .
I hope this information will help some people.
