I can't update iTunes. It says the feature you are trying to use is on a network resource that is unavailable.
Which particular .msi file does the message go on to say cannot be found? (Several different .msi files might be mentioned in this context: itunes.msi, bonjour.msi, AppleSoftwareUpdate.msi, etc.)
It says Click Ok to try again or enter an alternate path to a folder containing the installation package itunes64.msi in the box below

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the 
"DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?
I tried to use the windows installer cleanup and unfortunately I could not download it. The screen said that permission was denied.
Was it a Code 800A0046 error message?
I was able to get it to work. I had to do all the steps over again. However now I have deleted my entire iTunes library. Is there any way to get it back?
