iTunes wont install

Let's try doing a "Standalone" QuickTime install. It may not install and/or work properly, but the error messages we get then might help narrow in on the causes of the issue.

Download and save a copy of the iTunes64setup.exe installer file to your hard drive:

http://www.apple.com/itunes/download/

Download and install the free trial version of WinRAR:

http://www.rarlab.com/

Right-click the iTunes64Setup.exe, and select "Extract to iTunes64Setup\". WinRAR will expand the contents of the file into a folder called "iTunes64Setup".

Go into the folder and doubleclick the QuickTime.msi.

Do you get any error messages? If so what do they say? (Precise text please.)

Or does it install for you? If so, will an iTunes install now go through properly?

The configuration data for this product is corrupt. Contact your support Personnel.

That's a less common one.

Let's try the WinRAR-assisted standalone install one more time (in a slightly different way). Trying this because your QuickTimeInstaller.exe is also an installer bundle nowadays. (It doesn't contain the iTunes or Apple Mobile Device Support msis like the iTunesSetup.exe, but there's still a fair amount of stuff packed in there.) So it's possible that a different installer inside the bundle than the QuickTime installer is causing our grief here.

Launch WinRAR (Start > All programs > WinRAR > WinRAR). Browse to the iTunes64Setup.exe (or QuickTimeInstaller.exe). Select the file. Go "Commands > Extract to the Specified Folder".

Open the specified folder and doubleclick the QuickTime.msi

What error message do we get this time? Or does it go in this time?

🙂 Many thanks. Definitely the QuickTime componentry, then. I think, based on that, we're dealing with a rare variation (in terms of error messages) on the sort of problem that can also causes a "missing .msi" message.

Unfortunately, this sort of trouble has gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on June 25. First we have to find a copy of the utility.

Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)

If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.

Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any QuickTime entries and click "Remove".

Quit out of CleanUp, restart the PC and try installing iTunes again. Does the install go through properly now?

(If you do find a clean download site for the correct version of CleanUp, please don't tell me where it is. Without wishing to sound paranoid (although I grant it does sound paranoid), there is a non-zero chance that posting links to download locations for the utility here at Discussions leads to that download location being shut down.)

Sorry for the long delay in replying... The "Windows Install Clean Up" found no instances of QuickTime anywhere so I am still at the same stage.

🙂 No worries about the delay.

Launch CleanUp again and have a look up at the top of the list of programs Dave.

Do you see any entries in there that:

(a) Lack a program name but have an (All Users) followed by a version number in square brackets? If so, what is the version number?

(b) Lack a program number and a version number, and just have (All Users)?

(c) Lack everything ... it's just a blank line?
