My problem actually concerns iTunes which of course ultimately impacts our iPad. I cannot update iTunes on our HP Pavillion m7750 Media Center PC running Vista Premium. When I try to down load the iTunes update it errors out giving the message a problem exists with Windows Installer. Now, this is where the strangeness occurs. Windows installer functions perfect for all other downloaded installations. Why then is Apple's iTune the exception. Another strange occurrence is our iTunes/iPad password is no longer recognized. The password we are using is absolutely correct. The password is documented for safe keeping offline. Any advice in solving these two problems will be greatly appreciated.
