To install the product I had to go in an edit my regestry as it gave an erron on install. After getting it installed it then gave an error that the netlink settings could not be read, but I was still able to open the program. Everything seemed to work but if I clicked on the netlink tab it would say it could not connect which was expected, but when clicking on another tab after that caused the program to abend in erroe and shut down. So you don't click the netlink tab. Checking out the streets I found many major highways in the NC that were updated and their location changed not updated in 2007 even though the the changes were almost two years old. Found many major revisions on highways missing. Really bad software. One star is the lowest rating I could give this, no stars is better
