I've had to reinstall this software dozens of times. I finally figured out how to get it to work right. First off, you need to be connected to the internet as you install this. (Catch 22 if you planned on using your phone for that.) The main reason is so that you can update the software. I have a V3x which took several updates before it found the phone. (And I had to find the USB driver for my V3) In order to get it installed with vista, you might have to right click the moto desktop icon and "run as admin". After you get it working, you pretty much have to follow things in order when using the software. You have to plug the phone in, launch phone tools, use it, when done, close program, remove from PC. If you skip steps, esp if you're using he phone for internet, you run the risk of having to reinstall everything over again. Sometimes rebooting will help if it "cant detect the phone" after pulling the phone out before closing the program. Software is flakey, not user friendly but does work. Id bump the star up if I could but not over 3.
