Error installing iTunes

I have been trying to update iTunes and keep getting the following error:

There is a problem with the Wndows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor.

I uninstalled iTunes and all Apple products:
- Bonjour
- Apple Application Support
- Apple Mobile Device Support
- Apple Software Update
- iTunes

I tried to reinstall iTunes and I get the same error. However, Bonjour, Applie Application Support, Apple Mobile Device Support and Apple Software Update get installed.

I have tried using different browsers (Mozilla, IE). I disabled all startup items and tried with no success.

I have an iPhone that I want to update and music on the iPhone that I want to sync with my iTunes library.

I have tried unsuccessfully for days to get this to work so any help that you can provide is greatly appreciated. At this point I don't know if the problem is with Apple or WIndows XP.

I was able to download and install Acrobat Reader but was not able to install Safari from the Apple site.

try creating a different administrator account and use that to install iTunes

You could try the Windows Installer CleanUp Utility, then re-try removing iTunes first, and then QuickTime. Then Install the new QuickTime. Finally re-install the new iTunes, as described in this article. Scroll down for more suggestions>

I tried both suggestions and still have the same problem. Is there a way to deauthorize a computer that can't run iTunes so I can access the music library from another computer?

You are allowed to authorize 5 computers. After you've used up all authorizations then you can deauthorize all 5.

The computer that I'm trying to reinstall iTunes on is the one that needs to be deauthorized. How do I do that?

Maybe nothing new here, but the "How -To Geek" tends to explain matters in a clearer way:

You can not deauthorize a single computer without iTunes. However, you can deauthorize all five computers (including the one without iTunes) when you've reached your limit of five authorizations.
So if you absolutely must deauthorize this problematic computer - and you don't want to troubleshoot iTunes installation - then find four more computers to authorize then deauthorize all five at once.

correction: you do not need to find four more computers - the Deauthorize All option will become available if you have two or more authorized computers.
important note: you are allowed to use Deauthorize All option only once per year

Thanks for the help. I marked the question as partially complete only because I couldn't get iTunes installed. I was able to deauthorize the computer that was not able to install iTunes so I'm back in business.

Glad you've resolved the problem ...thank you.
