Just downloaded and installed this software after updating my netframework to 4.6.1 Had no trouble at all and noted that the expiration period is set for some time in July which is not 6 months. HOWEVER if you look in the bottom left-hand corner it indicates how many days are left and mine says 184 days remaining. My only complaint now is that I had to turn off the traffic monitoring as a notification popped up indicating that I am in an area which can’t be detected and my internet access might be cut off so I turned it off. I do like the feature this pro gives you by updating software, but some of the software, I do not use and don’t want it updated. I am exploring for better ways to handle this but I do think so far this software is pretty good and does what it claims to do so long as you are in an area which can be used for traffic monitoring. That part I do not understand. Any way folks….look in the bottom left-hand corner and you will see how many days remaining.
