How can I tell if the NavigatorV has been updated to version 8.1

Frequently Asked Questions: 

From the top menu select Help and then About ATP Navigator. A box will pop up and the version number is just under the Navigator logo.  If it says 8.1 you are good. 8.0 is the old version.

 

P.S. the welcome page is not version sensitive, it will show the same information on any version.
