Apple Application Support - What and why does this exists?

So I welcomed iTunes 9 on my computer and iOS4 on my music player (latter to a great commonly known regret). Now here is my question:
What is the "Apple Application Support" and why iTunes 9 must have it to run?
(Note: Normally many software products there have optional modules which one may wish or may not wish to install depending on required functionality.)
P.S. I did my Google "homework", so please kindly advise here substantively.

See the second half of the following user tip for some information about what Apple Application Support is:
[iTunes for Windows, QuickTime, and Apple Application Support|http://discussions.apple.com/thread.jspa?threadID=2355263]
The MobileMe Control Panel for Windows also uses Apple Application Support nowadays, as per:
[MobileMe: "CoreFoundation.dll was not found" or " Apple Application Support is missing" alert|http://support.apple.com/kb/TS2211]

  • I installed Itunes on my Vista, but error reads that there was no Apple Application Support installed and Itunes needs this in order to run

    I need to back up my iphone 5s on my old PC running Windows Vista SP2. After installing the proper iTunes that would run on Vista, I get an error as follows;
    "Apple Application Support was not found. Apple Application Support is required to run iTunes. Please uninstall iTunes and install iTunes again. Error 2 (Windows error 2)"
    I will appreciate any help. Thanks

    With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
    Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
    http://www.apple.com/itunes/download/
    Download and install the free trial version of WinRAR suitable for your PC (there's a 32-bit Windows version and a 64-bit Windows version):
    http://www.rarlab.com/download.htm
    Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
    Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
    Does it install properly for you? If so, see if iTunes will launch without the error now.
    If instead you get an error message during the install, let us know what it says. (Precise text, please.)

  • A later version of Apple Application Support is already installed on this computer.

    I am trying to update / install iTunes 12.0.1.26.  Apple Application Support will not install because it says there is already a later version installed.  There is not!  I have uninstalled after initial message and tried to reinstall but I still recieve the same message.

    Good Afternoon, JohnHT2!
    I think I have the fix to your issue.
    I've been experiencing the same issue as you describe above. The issue occurred for me during the upgrade process from version 11.4.0.18 to version 12.0.1.26 (which is the current version downloadable from Apple).  The installation sometimes appears to be okay, but the Apple Application Support fails to update correctly.  In other instances, the iTunes installation fails completely with error 1603 (which is generic "fatal error" code).
    Symptoms:
    Just some of the symptoms I've noticed in my environment.
    - In Programs & Features, there is no Apple Application Support to uninstall.
    - In Event Viewer's Application log, you may see Event ID 10005 from Source MsiInstaller, stating the dreaded error message "A later version of Apple Application Support is already installed on this computer."
    - In Event Viewer's Application log, you may see Event ID 1000 from Source Application Error, stating "Faulting application name: MsiExec.exe" along with a bunch of other error details.
    - When attempting to start iTunes, you may receive popup error "Apple Application Support was not found.  Apple Application Support is required to run iTunes.  Please uninstall iTunes, then install iTunes again".
    - Uninstalling and installing iTunes fails, including via the steps described for a "full uninstall" as described here on the Apple site (for instance: Troubleshooting issues with iTunes for Windows updates)
    - Installing Apple Application Support via the extracted MSI (AppleApplicationSupport.msi) fails with the same error: "A later version of Apple Application Support is already installed on this computer."
    - Installing previous versions of Apple Application Support fails with the same error (tried versions 10.7.0.21, 11.0.0.163, 11.0.1.012, 11.0.3.42, 11.1.0.126, 11.1.3.8, 11.2.2.3, 11.3.0.54, 11.3.1.2, 11.4.0.18).  (now that I know the issue, I'm confident any previous version of the installer will fail).
    - If you run the MSI installation with verbose logging, you may see lines stating: "PROPERTY CHANGE: Adding BNEWERPRODUCTISINSTALLED property. Its value is '1'." and "PreventDowngrade. Return value 1."
    There may be other indications, but these are things we ran into.  I'm trying to be detailed so that other folks who run into this issue may feel better about the below fixes being an option for them.
    Resolutions:
    I've found two ways to remedy the issue in our environment.  You can either use the Microsoft FixIt utility to clean up the previous installation for us, or you can edit the registry manually to repair the installation.  We're in an office and prefer not going computer-to-computer to fix everyone's issue independently, so we had to go via the registry.  I was able to fix it via both ways, though.
    Fix 1: Run the Microsoft Program Install Uninstall Troubleshooter.
    For this fix you will need to be logged in as an administrator for the computer.
    Here are the steps:
    Download and Run the Microsoft Program Install and Uninstall FixIt: [FixIt Link]
    In the troubleshooter, choose: Detect problems and apply the fixes for me (Recommended)
    Choose Installing
    From the list, select Apple Application Support and click Next. (it actually does appear here!)
    Select Yes, try uninstall. This step could take a while to process once it starts.
    Once it confirms it is fixed, click Next.
    Select "Yes, the problem has been fixed" and click Next.
    Finish/close the FixIt tool.
    Now the Apple Application Support will install successfully on your next attempt.
    - If you don't have iTunes installed, you can simply run the latest downloaded installer: iTunes64Setup.exe
    - If the other iTunes components are already installed, you will need to go to Programs & Features (or Add/Remove programs) and uninstall the iTunes program, then re-install the program from the downloaded installer: iTunes64Setup.exe
    - If you have the MSI, you can simple run AppleApplicationSupport.msi and carry on happily.  Make sure it's the right version of the MSI (right-click it, select Properties, go to the Details tab and verify the Comment line says "Apple Application Support 3.1").  If you don't know what an MSI is... ignore this and use the installer.
    iTunes should work perfectly normally for you now.
    Fix 2:
    If you're like me and you need to repair iTunes over a larger number of computers, then Fix 1 quickly becomes too time consuming.  Thankfully, a quick registry edit will resolve the issue as well.
    For more advanced users; if you're not sure what the Windows Registry is, please tread very carefully and make sure you back up the registry before you change anything!
    You'll need to be an administrator on the computer to do this.
    Start Registry Editor.
    In Windows 8.1, you can right-click the start menu (flag in the bottom-right corner) and choose Run.  Then type "regedit" and click OK.
    In Windows 8, go to the Start menu, click the magnifying glass (or just start typing) and search for "regedit".  The first result should be "regedit.exe" - click that.
    In Windows Vista, click the Start menu, then click the little arrowing pointing to the right (>) and choose Run.  Then type "regedit" and click OK.
    In Windows 7 or XP, click the Start menu orb, and choose "Run...". Then type "regedit" and click OK.
    Make a backup of your registry.In Registry Editor, right-click on "Computer" and choose "Export".  Save the file somewhere on your computer.  You'll probably never need it.. which are famous last words.  Better safe than sorry!
    Navigate to HKEY_CLASSES_ROOT\Installer\Products\ED0FAC38B3D873C46A13B2F861CE0313\
    If the key "ED0FAC38B3D873C46A13B2F861CE0313" doesn't exist, then go to HKEY_CLASSES_ROOT\Installer\Products and make sure "Products" is highlighted.
    Go to the Edit menu and choose "Find...".
    Do a search for "Apple Application Support".
    Your first result should be a ProductName value of "Apple Application Support".
    Verify at the very bottom of Registry Editor that your current location is "HKEY_CLASSES_ROOT\Installer\Products\[GUID], where GUID is an alphanumeric string that's 32 characters long.
    Right-click "Version" and choose "Modify".
    In Value Data, type 0 (the number zero) and click OK.
    Close Registry Editor.
    You should now be able to successfully install the AppleApplicationSupport.msi or re-install iTunes.  If, for whatever reason, it still detects the wrong version, go back to the Registry Editor and delete the entire key from above (so, right-click on the 'folder' named "ED0FAC38B3D873C46A13B2F861CE0313" and select "Delete").  Should never be necessary, though..
    In a Windows domain there are many ways to update the registry so use whatever works best for you.  I'll be adding this as a special extra step in our SCCM deployment.
    I hope this helps!  It took us a good many hours to track down what was stopping us from resolving the issue (and/or causing it to begin with).  Suffice to say we now have a whole bunch of users who are very happy to no longer get iTunes error messages when they log into their computers or attempt to start iTunes itself.
    Have a great day!

  • A later version of Apple Application Support is already installed on this computer - dead lock

    Hello,
    trying to solve itunes problems, i tried to completely uninstall itunes, as mentioned in article
    http://support.apple.com/kb/ht1925?viewlocale=es_ES
    (uninstall modules in order, verify uninstallation, reboot, and reinstall itunes)
    However, it wasn't possible to reinstall itunes. Digging in forum i found a method to install part by part the application, by means of unraring the installer .exe file and executing modules independently.
    The fist module: AppleApplicationSupport.msi won't install, because it does a check (erroneus check!!) and detects an inexistent version of Apple Application Support. It shows message: "A later version of Apple Application Support is already installed on this computer", and goes out.
    After that, i can install itunes, but do not work.
    I tried cleaning registry with msicuu2.exe, as mentioned somewhere to eliminate Application Support rests, but doesn't find any Application Support Installation.
    Locked. Can't use iTunes.
    Please, any help
    Thank you very much.

    Not yet. I tried apple telephone support, but couldn't get a definite answer.
    In my opinion a installer program should try to install in every case, overriding any version that could be degraded. It's a nonsense that a installer program goes out without installing, suposing there are no degradation issues of the installation software.
    Also, i think KB article http://support.apple.com/kb/ht1923 may need a correction, as it doesn't work fine always, and the cure is worse than the disease.

  • I am trying to download Itunes to my new Toshiba computer and it keeps saying Apple Application Support suspended and won't let me "undo" so I say no and it doesn't install....any options or a?

    I am trying to download Itunes to my new Toshiba computer and it keeps saying Apple Application Support suspended and won't let me "undo" so I say no and it doesn't install....any options or a?

    I suspect that you are saying that you can't download/install the latest version of iTunes. 
    All I can say is try removing and reinstalling the Apple software using the following:
    Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7
    If you have further problems with installing Itunes I suggest you post in the iTunes forum since you have an iTunes problem, not an iPod problem.  Also report the wording of any error messages. What they say is importent on resolving them.

  • My hp vista says I need to install apple application support. what is this?

    I'm trying to view some videos & it says I need to install apple application support. I have no idea what this is???

    If all you're trying to do is watch video files you already have on your computer, VLC is able to play virtually any video format.

  • When I try to use quick time player I get message "install apple application Support"  How do i get this?

    When I try to use Quicktime Player I get message "install apple application support".  Where do I go to get this?

    Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
    Download and save a copy of the QuickTimeInstaller.exe installer file to your hard drive:
    http://support.apple.com/kb/DL837
    Download and install the free trial version of WinRAR:
    http://www.rarlab.com/
    Right-click the QuickTimeInstaller.exe, and select "Extract to QuickTimeInstaller". WinRAR will expand the contents of the file into a folder called "QuickTimeInstaller".
    Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
    Does it install properly for you? If so, does the QuickTime Player launch properly now?
    If instead you get an error message during the install, let us know what it says. (Precise text, please.)

  • Apple application support part of itunes does not download

    Hey there Shonny1961,
    It sounds like you have uninstalled iTunes and reinstalled it, but the Application Support info is not installing. I would use either of the following articles to uninstall not just iTunes but its associated softwares as well, and in the correct order. Then use the links in the article to download and install a fresh copy of the application:
    Remove and Reinstall iTunes and other software components from Windows XP
    Or:
    Remove and reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8
    Thank you for using Apple Support Communities.
    All the best,
    Sterling

  • I have downloaded itunes to my computer which has windows based 7 and I get an error saying Apple Application Support was not found error 2.  What do I need to do.

    I have downloaded itunes to my computer which is windows 7 and I get an error 2 which says Apple Application Support was not found does anyone know how to overcome this error?

    Install 7-Zip (free), or a free trial of WinRAR, and use one of them to extract the contents of the iTunesSetup.exe or iTunesSetup64.exe installer file, then try installing AppleApplicationSupport.msi as a standalone component. Even if it won't install you may get a more useful error message as to why not.

  • "apple application support was not found" now what?

    Installing itunes on Vista just to manage content on my ipad and I got the above message. How do I fix that?

    Hi b noir,
    I've been following your posts for my iTunes compatibility problems with Vistas.  So far, progress has been steady - but now I'm stumped.
    Apple customer service wanted me to Uninstall/Reinstall iTunes - intending to walk me through the problematic new-device setup.  Prior to now, iTunes has had quirks with Vistas, but we were running just fine.  However, per Apple, I Uninstalled and now - I just cannot get it Reinstalled. 
    I cleared a few hurdles until I got this "Apple Application Support not found error 2" message.
    Again, I followed your steps and after trying the standalone AAS install, I get the following message:
    "A later version of Apple Application Support is already installed on this computer."
    So, between these two messages:
    AAS not found error 2
    "A later version of Apple Application Support is already installed on this computer."
    I don't know what to do next.
    Can you please advise?

    (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 Apple Application Support entries and click "Remove", as per the following screenshot: 
    Next, select any Apple Mobile Device Support entries and click "Remove", as per the following screenshot: 
    Next, in the list of programs that appears in CleanUp, select any Apple Software Update entries and click "Remove", as per the following screenshot:

    (That should reinstall the three dodgy components.)

  • Having some trouble with Apple Application Support...

    So, I recently purchased a new 3G iPod Touch. I already had iTunes installed, so I did not think I would have a problem. However, it prompted me to update to iTunes 9. I didn't give it much thought when it froze the first few times and simply thought it was a download error, so I just stopped the installation process and retried. After letting it run, the process gave me an error message prompted from the "Publishing Product Information" status. I tried uninstalling all the Apple-related software on my computer in hopes that it would work to no avail. I received the same message. Then I tried going through this list of troubleshooting procedures [http://support.apple.com/kb/HT1926?viewlocale=en_US] which also did not work. I did some research and found that some individuals had luck with extracting each of the separate install processes from iTunesSetup and proceeding to install each one separately. One person claimed that by starting with AppleApplicationSupport, he somehow overcame the issue. However, once the installation process reached a certain point [also the Publishing Product Information status], the process froze and a short while later fed me an error message (the error reads: 'Microsoft.VC80.CRT,version="8.0.50727.4053",type="win32",publicKeyToken="1fc8b 3b9a1e18e3b",processorArchitecture="x86"'. Please refer to help and Support for more information. HRESULT: 0x800736FD). I'm at a loss as to what to do now.

    Some experimental advice in this context. (I generally try this for different install errors than the publickeytoken jobbies.)
    We might be able to get things to go through better if we do a "standalone" Apple Application Support install, and then do the iTunes install.
    First, uninstall iTunes again.
    Now go "Start > All programs > Apple Software Update". *Do not install anything yet.*
    In ASU, go "Tools > Open Downloaded Updates folder". Delete any files currently in there.
    Go back into ASU. Select the iTunes offering. Now go "Tools > download only".
    After the downloads complete, go back into the Downloaded updates folder. Doubleclick on the AppleApplicationSupport.msi file to do a "standalone" AAS install.
    Does that one go through okay this time?
    If so, doubleclick on the iTunes.msi this time. If that goes through okay, does iTunes launch without the error message now?

  • HT1926 when i try to install Itunes for windows I get a message that says the older version of Apple Application Support cannot be removed contact technical support group.

    I also get a message that says the Apple Mobile Device Support cannot be removed.
    then Itunes ends the installation due to errors.
    These two files show up in the control panel and when I try to delete them it says they are on a network resource that is unavailable.

    (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):
