If you have Windows 7 and are using an iTouch, it will not connect..
If you have Windows 7, good luck trying to get this to connect. I read and performed the advice provided on Logitech's support forums (including disabling firewall and allowing Logitech public and private access through Windows firewall) but still could not connect. I then proceeded to contact Logitech whose customer service representative was absolutely useless as he was strongly believed that the iTouch is not compatible with the TouchMouse Server even though Logitech's own website says that it is compatible. Overall, complete waste of time.
The ability to connect through Windows 7 64-bit OS using an iTouch. More
