When I run the iTunes x64 installer, it returns an error "This iTunes installer is intended for 32-bit versions of Windows. Please download and install the 64-bit iTunes installer instead." The computer has Windows 7 Enterprise 64-bit. I have uninstalled all Apple products and deleted all folders including Bonjour, Quicktime, etc. Also tried running in compatibility mode as a previous version of Windows. What I found odd is the program attempts to install in Program Files (x86). Shouldn't it install in Program Files if it's a 64-bit application?

    Doublechecking something. By any chance, did you use the PC Mover utility to move the iTunes application and your iTunes content from a 32-bit system to your current 64-bit system?

  • Don Franko Level 1 (0 points)

    No. PC Mover was not used. When I first started working on the machine Apple Software Update, Mobile Device Support, and Bonjour were all installed, however neither iTunes or QuickTime were, so most likely, there was a previous install of one or both.

    Okay. Doublechecking a couple of further things.


    The name of the installer file you're using is "iTunes64Setup.exe"?


    When you've attempted to uninstall iTunes, Bonjour or Apple Mobile Device Support from the PC, have you got the same error message as when you try to install iTunes?

  • Don Franko Level 1 (0 points)

    Yes. The installer is iTunes64Setup.exe. When it launches, it shows x64 in the corner as the version.


    I have not had any issues uninstalling Bonjour, Mobile Device Support, or the Software Update. They each uninstall and remove their folder from Program Files.

    Hmmmm. We'd better see if there's any damaged iTunes installation configuration information on the system that might be throwing a misleading message.


    (1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the /___sbsstatic___/migration-images/189/18990253-1.gif "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):




    (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.


    (Do not remove anything at this stage. We're just having a look.) Even though iTunes, AMDS and Bonjour have all been uninstalled are there any entries for any of iTunes, Bonjour or Apple Mobile Device Support appearing in the list of programs in CleanUp?

  • Don Franko Level 1 (0 points)

    Just got a chance to run this. Yes, the Mobile Device Support and iTunes are both listed in the Windows Installer Clean Up.

  • b noir Level 9 (72,060 points)

    Okay. I think those must be the culprits with the error messages.


    Launch CleanUp again. Select the iTunes and AMDS entries and click "Remove". Restart the PC and try another iTunes install. Does it go through properly this time?
