I have tried all versions of Motorola Phone Tools from 2.0 up to 5.13B and have tried to run it on WindowsXP and Windows Vista I have tried to use it with various Motorola phones and if I remember correctly actually got it to work once a long time ago and don't even remember which phone it worked with. The problem is though, even when you get it to work it doesn't last. Eventually it just quits working. I wouldn't recommend this program to anyone. Another irritant I have with the program is everytime you install the program it has to update itself several times which takes hours on my connection and then doesn't save the update files so when you have to re-install it again and again to try despearately to get this expensive program to work you spend your whole day for nothing.
