iPhone not working with Windows 7. Message asks to install 64-bit version

Make sure your computer is 64-bit by going into..Start>Control Panel>System and Security>System

It should say whether its 32-bit or 64-bit.

Have you tried installing the 32-bit version?

Actually I did Google your problem and people have been saying they cant find that program either.

Sorry. For Windows 7 its this one. http://support.apple.com/kb/HT2292

My husband switched to 32-bit Windows 7 because a number of software packages he uses aren't compatible with 64-bit 7.

In 32-bit, iTunes syncs his phone with no issues.

I'm having the same exact problem. I've uninstalled quicktime and iTunes, restarted my computer and then re-installed iTunes, but no luck. Keep getting the same message: required software is not installed. Run the itunes installer to remove itunes, then install the 64-bit version of itunes. BTW, I used iTunes a couple of days ago with no problem. I don't know what changed.

Does anyone know what to do???

Once again, I provided a link that should resolve this issue.

The MSCONFIG workaround requires I-tunes and I-phone code to be installed on the machine. The problem is that I-tunes will not install on XP 64-bit machines. It will install on Vista but NOT XP. MSCONFIG requires the user to allow code that can't be on the machine until it's been installed! Apple staff have confirmed this to me over the phone after I spent half a day trying to figure it out.
There is an option, which I know some Apple staff are aware of, which has been set up by a Japanese kid and can be found here:

There are also a couple of 3rd party I-pod readers which, if I name them, will probably get me kicked off the list. Why the f*ck can't Apple sort this out. XP 64 bit has been around for FIVE YEARS!!!

Im having problems on 32 bit Win 7 as well. iTunes 9.0.3.15 does not recognize iPhone.
