Windows Installer Error Message.

Question

Hello, I am trying to fix my iTunes/QuickTime, which seems to be broken for some reason. I am trying to uninstall it and reinstall it but I get the following error message.
"The feature you are trying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'QuickTime.msi' in the box below."
I have found a bunch of different QuickTime.msi files and been selecting it on the error message (you know how it says browse for file and select QuickTime.msi..) but it shows the following messages.
"The file 'C:\Documents and Settings\Nick\Local Settings\Application Data\Apple\Apple Software Update' is not a valid installation package for the product QuickTime. Try to find a installation pacage 'QuickTime.msi' in a folder from which you can install QuickTime."
(Depending on which QuickTime.msi file I choose, they are all in different locations, I don't really know why..)
Anyways, if anybody has any ideas on how to resolve this it would be much appreciated. Thanks very much!

When you get messages about msi files you usually need to do an installer clean up.
Here is a method for removal of iTunes, Quicktime etc followed by clean up and install.
Download a fresh copy of iTunes and the stand alone version of Quicktime (the one without iTunes)
http://www.apple.com/quicktime/download/win.html
http://www.apple.com/itunes/download/
Download and install Microsoft Installer cleanup utility, there are instructions on the page as well as the download. Note that what you download is the installer not the program – you have to run it to install the program.
To run the program – All Programs>>Windows Install Cleanup

Now use the following method to remove iTunes and its components:
XP

Vista
http://support.apple.com/kb/HT1923
*If you hit a problem with one of the uninstalls don't worry*, carry on with the deleting of files and folders as directed in the method.
When you get to deleting Quicktime files in the system32 folder as advised in the method, you can delete any file or folder with Quicktime in the name.
Restart your PC.
Run the Microsoft Installer Cleanup Utility. (Start > All Programs > Windows Install Clean Up)
Remove any references you find to the programs you removed - strictly speaking you only need to worry about those programs where the uninstall failed.
If you don’t see an entry for one of the programs that did not uninstall, look out for blank entries or numeric entries that look like version numbers e.g. 7.x for Quicktime or 1.x for Bonjour.
restart your PC
Install the stand alone Quicktime and check that it works.
If it does, install iTunes.
