Install problem - Says feature is on an unavailable network resource

I'm a two-year iTunes user, and always upgrade to the latest version as soon as it's available. Now I own an iPhone, too, so iTunes is critical. I'm also a Systems Analyst by profession, and can usually figure these things out (I think this is only the second time I've ever had to post to a message board to ask for help), but I'm stumped on this one.

Last week I downloaded the latest install module, saved it on my hard drive, and ran it. When the install was almost complete, I got a Windows message that said: The feature you are trying to use is on a network resource that is unavailable.

I'm signed on as the administrator, and I haven't changed anything on the PC that I can think of that would cause this problem. There's a drop-down box at the bottom of the window that lists the "invalid" path:

C:\Documents and Settings\NetworkService\Local Settings\Application Data\Apple\Apple Software Update\

I agree that this is an invalid path, which seems to explain why I'm getting the message above -- there's no "Network Service" folder on my hard drive -- but I don't understand why it's thinking that this path is where my iTunes packet would be located.

I try to manually point it to a path where a copy of the iTunes packet seems to be located, and I get another Windows message: "The file 'C\Doucments and Settings\...\Local Settings\Application Data\Apple\Apple Sortware Update\iTunes.msi' is not a valid installion package for the product iTunes. Try to find the installation package 'iTunes.msi' in a folder from which you can install iTunes." (Replace the ellipse in the path above with my Windows user ID.)

I've repeated the process several times, trying to point it to every instance of iTunes.msi I can find anywhere on my hard drive (hidden/system folders as well as regular folders), for any iTunes version. (There are numerous.)

I've also tried to uninstall iTunes, and I get the same "The features you are trying to use ... " error as above, followed by the "is not a valid installion package for the product iTunes" message, followed by this message: "The installation source for this product is not available. Verify that the source exists and that you can access it."

When I try to access iTunes, it's no longer there. I get this message: "This action is only valid for products that are currently installed."

Can anyone help? Thanks!

Bob has already given you the best answer to this. I'll just flesh it out in a little more detail.

First, head into your Add/Remove programs and uninstall your QuickTime. If it goes, good. If it doesn't, we'll just attend to it when we attend to iTunes.

Next, download and install the Windows Installer CleanUp utility:

Description of the Windows Installer CleanUp Utility

Now launch Windows Installer CleanUp ("Start > All Programs > Windows Install Clean Up"), find any iTunes and/or QuickTime entries in the list of programs in CleanUp, select those entries, and click “remove”.

Next, we'll manually remove any leftover iTunes or QuickTime program files:

(1) Open Local Disk (C:) in Computer or whichever disk programs are installed on.

(2) Open the Program Files folder.

(3) Right-click the iTunes folder and select Delete and choose Yes when asked to confirm the deletion.

(4) Right-click the QuickTime folder and select Delete and choose Yes when asked to confirm the deletion. (Note: This folder may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)

(5) Delete the QuickTime and QuicktimeVR files located in the C:\Windows\system32\ folder. Click Continue if Windows needs confirmation or permission to continue. (Note: These files may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)

(6) Right-click on the Recycle Bin and on the shortcut menu, click Empty Recycle Bin.

(7) Restart your computer.

Now try another iTunes 7.6 update. Does it go through properly?
