Cant install itunes due to "Unsupported 16 bit application" error

Hey everyone.
A couple weeks ago my iTunes got messed up after my pc froze. Since then, iTunes will pop up with "installing" when my iPod is charging, but nothing happens.
I have tried to re-install with the latest version and with old versions, but I keep getting an error that says "Unsupported 16 bit application."
Is the anyway I can fix this and get iTunes to install?
Thnaks for your help.

If I remember correctly and if you do some research 16-bit execution is not supported on 64-bit Windows.
See results of a Google for

How can I run 16 bit programs in Windows 7 64-bit? :
"16-bit programs can't run on 64-bit windows 7 natively."

    For general advice see Troubleshooting issues with iTunes for Windows updates.
    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
    Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
    The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if AAS won't install normally.

    After following instructions for three different solutions that did NOT work; I found the solution that did work
    on the support site for Syamntec.
    Readers - Please, you must be VERY familiar with pc jargon and windows vernacular to accomplish the reset
    of ALL the permissions in your registry.
    Follow the ditrections below and pay attention to the notes for those running 64bit Win7.
    Step one, back up the registry.
    Step two, go to the MS KB: http://www.microsoft.com/downloads/details.aspx?FamilyID=e8ba3e56-d8fe-4a91-93cf -ed6985e3927b&displaylang=en and download the file that installs subinacl. It is an MSI file, and will do a quick install of a few Microsoft files.  Hint: Look in the folder listed below, "subinacle.exe" may already be there.
    Step three, create a batch file (subinacle.bat) with the following commands:  (Use Notepad - copy & paste, not the red stuff)
    cd /d "Program Files\Windows Resource Kits\Tools" (only for 32bit/x86 machines)
    subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f
    subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f
    subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f
    subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f
    subinacl /subdirectories %windir%\*.* /grant=administrators=f /grant=system=f
    secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
    For 64bit machines substitute for first line of bat file:
                        cd /d "c:\program files (x86)\windows resource kits\tools"
    Step four, run the batch file. Let it run until the Command Prompt screen closes, may take 30 minutes or more.
    Step five, reboot the machine and run the install again.
    Ladies and Gentlemen; this worked for me and allowed immediate installation of two application packages I had been trying for three months!  (Including ITunes 10.5)

  • I can't install itunes on my windows 8.. error appears says this : error microsoft. vc80.crt type="win32".version="8.0.50727.6195"

    Why I cant Install itunes in my windows 8? error appears and it says:

    please healp me

    These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes trouble cleaned up en passant.
    Go into your Windows update and try to check for new updates. If updates install, stock up on the ones you're behind on, restarting the PC if requested to do so. After the restart, try installing iTunes again. Does it go through this time for you?
    If windows updates fail to install, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? (For example, 8007000B.)

  • I cant install itunes it keeps on saying "service apple mobile failed to start" and i keep on reinstalling it but that keeps on coming up

    i cant install itunes it keeps on saying "service apple mobile failed to start" and i keep on reinstalling itunes but i keep on getting the message.

    Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (Later)
    Remove all of these items in the following order:
    iTunes
    Apple Software Update
    Apple Mobile Device Support
    Bonjour
    Apple Application Support
    Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
    See also HT1925: Removing and Reinstalling iTunes for Windows XP or HT1923: Removing and reinstalling iTunes for Windows Vista, Windows 7, or Windows 8
    Should you get the error iTunes.exe - Entry Point Not Found after the above reinstall then copy QTMovieWin.dll from:
    C:\Program Files (x86)\Common Files\Apple\Apple Application Support
    and paste into:
    C:\Program Files (x86)\iTunes
    The above paths would be for a 64-bit machine. Hopefully the same fix with the " (x86)" omitted would work on 32-bit systems with the same error.

  • Cant install itunes 10.6 no matter what i try! (Windows installer package error)

    I cant install itunes !
    I downloaded the latest version from the offcial site, and everytime i try to install it it stops half way due to Windows Installer Package error. It says I'm missing a program required to continue this installation.
    I've tried removing all the files with removal tools, running it with admin rights, disabling firewalls, User account controls, updated my Windows update to the latest version. Read all the threads and tried everything but it still doesn't work.
    Does any1 have any suggestions?

    Download and save a full itunes setup file.
    Use Winrar to unzip the file into a folder.  Then right mouse click the file AppleSoftwareUpdate.msi from that folder to install.
    If you don't have winrar, you can go to this link to download a free trial version.

  • HT1926 cant install itunes on windows 7 64bit . cant run a required dll

    i cant install itunes on windows 7 64bit . when i run the setup and reach the status : "performing installation checks" , it said "there is a problem with this Windows Installer Package . A Dll required for this install to complete could not be run.v..v" what should i do now ?

    That's a bit rarer. It's a 1723 error message. (1721 and 1722 are more common.)
    Even though the following user tip is about slightly different errors (the 1721 and 1722), perhaps try it with your one too:

  • Cant install itunes 10.5

    why i cant install itunes 10.5 on my alienware windows 7 64-bit? ive been trying for 3 days now,still it says error on windows installer package. can anyone help me??

    Open regedit using "run as administrator".
    Go to the registry key:
    HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionInstallerUserDataS-1-5-1 8Components
    ...and selected the folder DA42BC89BF25F5BD0AF18C3B9B1A1EE8
    (there are three folders with very similar names A,B & C you want the first one)
    Right click & choose Permissions
    Click Advanced, and then the Owner tab
    Type  (not administrators) in current owners field and check the box to replace the owner on subcontainer and volumes
    Apply settings and then click Permissions tab. Once again, add  (not administrators) to the list of permission entries, then click edit and check all permission boxes. Also click the 2 bottom boxes concerning the inheritable permissions.
    [Note: In my case I was a member of administrators and administrators was already set in all of the above settings - I've no idea why it needed to be set to my user rather than the administrator group, anyway it solved the problem for me]
    Click OK
    Now back on the main permissions tab, add  in the user name window and then check full control and read checkboxes. Click OK.
    On the menu bar click file > exit
    But if u have the message pop up more then once then just make the permissions for the entier S-1-5-18Components folder

    I pulled my brains out trying to figure this bug out and I may have a solution for you.
    All of it installed fine in my desktop, but a friend's laptop got the error you mentioned on quicktime, itunes, flash, officeXP and about anything else I tried to load for him.
    If you look in: C:\documents and settings\<username>\Local Settings\Temp there will be an iTunes install log...open it in Notepad and see if it isn't exiting with a 1619 error while running msiexec.exe
    If this is the case, this fix should work for you.
    Seems some configurations of XP (and possibly Vista) aren't allowing full administrator rights to the account you set up when you installed XP (even though User Editor says you do have those rights.)
    I read 2 MS articles and turned off simple file sharing, then gave ownership of the entire C: drive to the administrator. Logged the admin account off, logged his "admin" account in, and then gave rights to his personal directory to his account (c:\docs and settings\<username>)
    Once I did that, every install that had previously errored out performed flawlessly.
    The MS articles in question:
    http://support.microsoft.com/?kbid=316309 (1619 error)
    and
    http://support.microsoft.com/?kbid=308419 (how to set special permissions)
    Hope this helps!

  • Installing iTunes on Vista 64-bit

    *Looking for 64-bit support from Apple*
    I'm running the 64-bit version of Windows and was disappointed to find out that Apple does not support it (see http://docs.info.apple.com/article.html?artnum=301301 ). I tried to install iTunes anyway and the installation failed. This forum didn't provide any initial solutions that I could find so now that I've figured it out I thought I would post a solution for those that come looking.
    *How do I know if I have the 64-bit version of Vista?*
    Press the windows key and the Pause/Break key at the same time (the pause/break key is normally in the upper right corner of the keyboard). On the window that appears look for the label "System Type." next to it you will see text indicating whether you have a 32-bit or 64-bit version of Vista.
    *What Will happen if I try to install Vista?*
    You experience may varry, but when I tried the installation ran for a while and ended with a message saying Quicktime could not be installed. I checked the Programs menu and iTunes was not listed after this failure.
    *How do I successfully install iTunes on a 64-bit edition of Vista?*
    When you download iTunes select the option to save the installation instead of running it immediatly. After the download completes right-click on the installation and select properties. Under the "Compatibility" tab check the box that says "Run this program in compatibility mode for." Ensure that "Windows XP (Service Pack 2)" is selected. Also check the box that says "Run this program as an administrator." Click on okay and the install iTunes.
    *Will this also work for XP 64-bit edition?*
    I don't know.
    *I've successfully installed iTunes on my 64-bit machine. Can I use it to activate my iPhone?*
    No.
    If you try to activate your iPhone you will receive a message saying "Please connect iPhone to a computer running a 32-bit version of Windows XP (SP2) or Windows Vista."
    *What happens if I set iTunes to run in Compatibility mode*
    iTunes will detect that it is running in a compatibility mode and suggest that you turn the mode off and restart iTunes. Since it recognizes that it is running on a 64-bit machine it will still refuse to activate an iPhone. Bummer.
    *If I activate my iPhone on another machine then can i transfer content to it on Vista 64-bit edition?*
    Nope. iTunes will instruct you to connect the phone to a 32-bit machine.

    Yes the forum has been misbehaving recently hence my double post. Ther should be an edit button, but it is only present for a few minute.
    The error you are getting has certainly been associated with a failure of Windows updates, but I don't know if the one you mention is an issue.
    The microsoft link to the update problem is;
    http://windowshelp.microsoft.com/Windows/en-US/Help/ca7d15d7-8ee3-4993-bd01-753d adc904121033.mspx
    That's about as far as I can go with this I am afraid.

  • Can't install itunes on windows 64 bit system

    I tried to install itunes on my 64 bit machine, but with verson 6.0.5, it says this software doesnt support 64 bit systems. I tried to install an earlier version i think its 6.0.4.2 not sure, but it does install on my computer. When I try to open the program and quicktime, I get error box saying the program had a problem and couldn't open. Is there anyway to fix this problem, and is there a way to have the newest version of itunes to work on windows 64 bit?
      Windows XP Pro  

    iTunes and QuickTime have never been supported on the 64-bit version of Windows (look here for the official statement). Some people have managed to get it working (at least tolerably), but from what I've read, a recent update from Microsoft has caused a lot of problems. You might try rolling back recent Windows updates and see if you can get things working again.
