Unable to sync iPhone 4 with iTunes on Win 7 Home Premium 64bit

My old computer crashed and I'm now on a new PC with Windows 7 Home Premium 64-bit.


I installed the latest iTunes successfully, but found that my iPhone 4 is now not syncing with it.

It can detect the phone, but it's not adding or deleting anything - apps, music or photos. I used to be able to select a Photo Folder to sync from the PC hard drive, but now it no longer works. It, however, works well with my notebook which is running on Win Vista.


There is no error message, the sync and backup apparently goes on only for a few seconds, and then iTunes says it is searching for which apps to install but nothing changes. Even when I've clicked Apply.



I've also tried closing iTunes and I've rebooted the phone but no dice. I've also uninstalled iTunes to reinstall. Doesn't work either. And yes, I installed with the 64-bit installer.


Any help or advice would be much appreciated!

Did you install the latest version of iTunes?

Did you ever have iTunes on another computer. Also check to see if your account is activated with iTunes.

Yes, there was iTunes on another computer that crashed, and it was a Win XP.

Also, yep -- signed on iTunes account. Also signed in to the app store on my iPhone itself.

Have you tied reinstall all Apple software?

Yes, I did that twice. Following the instructions here:
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP

I did not get any errors from either uninstalls or re-installs.

Then I would try to do a restore of the phone. If that doesn't work then its something to do with Windows.

That's what I suspect too.
Thanks for the response.

I will be in and out till very late for the next couple of days, so I'll try a phone restore when I have more time. Will continue on this thread with my findings.
