iTunes 10.5 will not install on Windows XP

Getting the same thing. If I find a solution will let you know!

In this case, I think either 10.5 doesn't support XP, or you need to use Microsoft Installer Cleanup (though that seems to have disappeared).

Apple software installers and Windows have never had a good relationship. Have they?

I had this problem on XP SP3 too. I went to the Control Panel, Add or Remove Programs, then pressed "Remove", then "Repair" on all the Apple stuff in there. I had three: "Apple Application Support", "Apple Mobile Device Support" and "Apple Software Update", then rebooted. Wasted so many hours on this. I hope this works for you.

Now to waste more hours trying figure out why I can't restore from backup or even get all my music and videos to sync :/

It installed ok on my WinXP box but now all my music sounds like you're hearing it over a bad phone connection -- all scratchy and distorted. Real Player does fine. Very strange. Almost seems like some kind of weird driver issue.

This is what I did to successfully installed itunes 10.5 and everything works and my iphone is in good shape with ios 5.0...

Step #1) Go to Apple download and update your Quick time to 7.7 (do not update anything else cuz you can't)

Step #2) Go to control panel, add/remove programs, and click on "apple application support", click change, and repair. Do same to apple mobile devise support, click change and repair, then to apple software update, click change and click repair.

Step #3) Push Ctrl, Alt & Delete to see if your "bonjour" service is running. If not you have to turn it on by going to control panel, Admin tools, then services.

Step #4) Now you can click on "itunessetup.exe" file that you downloaded. If you haven't you need to download.

Step #5) Now it will install without any problems.

Step #6) To sync with your iphone you MUST restart your computer.

Thanks for the info but unfortunately QuickTime is in the same state of limbo as all the other apple software on my pc - can't remove, repair, or reinstall, all with the error message that the msi file in my documents/local~/temp dir is not valid. I have installed iTunes 10.5 on my laptop and am waiting for the dust to settle on 10.5 and iOS 5.0 before syncing my iPad to the laptop. I have a feeling that 10.5 will be upgraded soon for more robust installations on pcs. One would hope, anyway.

Thank you!! Your directions worked!! I copied them below for others to benefit from:

Your advice worked so well!!

You're awesome!!

Thank you soooo much!

I have been tring to install this for HOURS. Last night I got the first error messages. It was a nightmare. I decided to uninstalled everything apple related and see if I could reinstall it all by myself and I got the same error message.

I though it was a windows XP issue or that my Windows Installer was corrupted. I spent hours reinstalling my windows services and using crazy command prompts and I still got the error messages.

This morning I keep trying other things and when I was about to quit and give up on this I decided to google "problems installing new Itunes 10.5 with windows XP" and bingo I found you! I can't believe it was something that easy. I downloaded Quicktime 7.7 and although I got the same error message again I left the window open and I skipped to your second step to repair all the apple files. Then, automatically the quicktime.exe continued its downloading.

After all of this I finished with the next steps and EVERYTHING worked!!!

you're amazing! thank u thank u!!!

Solution I got from iTunes is to uninstall iTunes and all its components. However, I was able to download directly from www.techspot.com Not sure why iTunes hasn't fixed this problem so that you can download directly from apple.com

I need to clarify - their solution was to uninstall and reinstall...

I followed the directions 4-5 times and still cannot get iTunes 10.5 to install on Windows XP SP2. Apple Support will not help me unless I purchase their support plan. I removed iTunes 10.4.1 as part of the process and now I cannot re-install it. I currently do not have a way to sync my iPad nor iPhone. I was planning to update my iPhone to iOS 5 but obviously cannot do that without running iTunes 10.5 on my computer. Please help!
