Hi all,
I have a 3rd. gen iPod and a 5th gen iPod, and one iPod Nano, but none of the three are able to communicate with my computer.
I installed iTunes a few year ago when I bought my 3rd. gen iPod, and everything worked very well, but one day the software stop working and I installed the last version of iTunes wich I downloaded from apple.com/itunes, then the problems started:
1. I am keep getting this error message:
"The software required for communicating with the iPod is not installed correctly. Please reinstall iTunes to install the iPods software"
Here is the image: (its in Spanish since Im from Mxico)

Im using the Windows XP sp2, with iTunes 7.3, well in fact, I got the error with any release of iTunes.
2. I reinstalled the iTunes for about 4 times and the problem still there
3. I think, I already tried everything:
a. Re-installed iTunes, with 7.3.2 release.
b. Un-install iTunes, and remove every directory the application left on my computer
c. Erase the Apple Software entry on the windows registry.
Other thing: if I try to install iTunes not having plugged the iPod to the computer, the installation wizard, sends an error message: "Drive G: is not valid", and the installation aborts.
Im stuck by now, I do not know what else to do, an none of my iPods are able to be recognized by iTunes, so, as a workaround Im using RealPlayer for syncrhonize my music with iPod, but Im missing the nice features of iTunes and Im not able to synchronize video or pics.
I hope somebody can help me or give some hints on how to solve my problem.
Thanks! cheers!
