Keyboards and Keyboard/Mice Combo Sets

[g12345567]

I have old itouch Logitech keyboard in perfect working condition. I know itouch software was discontinued and not available for windows 7 64bit.

By default some of the buttons still work like.Colume, mute, media player, home, favourites, scroll, forware, previous.

One button that doesn't correctly that I would like to get working is email.  Currently when the E-Mail button is pressed it points to an invalid link, tring to load "URL.DLL". I assume that a redisatry line is needed to be changed to fix the invalid link for the E-MAIL button so that it points to the email application..

Anybody know if this can be changed in windows 7 and what settings I need to change to fix the invalid E-Mail button link? or a list of all the other woring keys that can be changed.
