Can anyone please help me with this error: "Apple application support was not found... Error 2"

I've followed the instructions by removing all Apple files from my laptop, but when I reinstall the iTunes software it still comes up with this message:


"Apple application support is required to run iTunesHelper. Please uninstall iTunes, then install iTunes again. Error 2"


Thank you

iTunes for Windows XP, Windows XP, 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:



    Download and install the free trial version of WinRAR:



    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, does iTunes launch properly now?


    If instead you get an error message during the install, let us know what it says. (Precise text, please.)

    I would suggest following this article:

    Also, trying following error 2 in this article:

    Let me know if it helps.

    Also, check your add and remove programs on your computer and see

    if Apple Application Support is listed.

    The six components upon install of itunes is as follows:

    1. iTunes
    2. QuickTime
    3. Apple Software Update
    4. Apple Mobile Device Support
    5. Bonjour
    6. Apple Application Support (iTunes 9 or later)

    Also, follow this article thoroughly:

    Let me know if it helps.

    iTunes "Apple Application Support is required... Error 2" and possible fix.


    I know this is a bit late but I came accross this thread trying to resolve this same problem and came up with a solution that worked for me, so thought I would share it here too. I hope it helps someone else.


    I just resolved this on Win Vista (should apply equally for Win7 too). Please uninstall iTunes before proceeding though. I'll walk you through the process I followed, if you like you can jump straight to the Solution section.



    The initial error during the installation of iTunes was:

    An error occurred during the installation of assembly '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:0x8007054F


    The error (after installing iTunes) when trying to run iTunes was:

    Apple Application Support is required to run iTunes. Please uninstall iTunes, then install iTunes again. Error 2 (Windows error 2).


    After trying various fixes around the forums I came across this MSKB article, which relates to the first installation error:


    This lead me to trying to install MS Visual C++ but I received the following error trying to install that:

    Error 1935.An error occurred during the installation of assembly ‘Microsoft.VC80.ATL,type=”win32”,version=”8.0.50727.762”,publicKeyToken=”1fc8b3 b9a1e18e3b”,processorArchitecture=”amd64”’. Please refer to Help and Support for more information. HRESULT: 0x80070BC9. Assembly interface: IassemblyCacheItem, function: Commit, component: {837BF1EB-D770-94EB-A01F-C8B3B9A1E18E}


    Note: The installation of VC++ rolls back when it fails.



    Through this error I found this MSKB article:


    The Automated MS "Fix It" msi package didn’t work.


    Note: Please backup your registry first (see the above MSKB article for instructions).


    I opened the registry and (as instructed in the MSKB article) deleted the following keys:


    • PendingXmlIdentifier
    • NextQueueEntryIndex
    • AdvancedInstallersNeedResolving


    Reboot and reinstall iTunes.

    First make sure you uninstall iTunes. When you go to reinstall iTunes right click on the installer and choose "Run as Administrator". That should solve the issue.

    Avarix.  That is the best and easiest solution!!! Thanks.

    I  had the same problem, trying for 2 days... installing and uninstalling iTunes on Windows7 and nothing worked.

    Till I found the help on YouTube


    Try this if you are having truble with iTunes.


    Go to your C drive

    Windows folder

    system32 folder

    etc folder

    take the host file in it and place it on you desktop

    shut the window down and do the same thing again, only with replacing the host file back into the etc folder


    Problem solved at least for me

    Its doing the same to me and im mad i can't even do anything about it everytime i try it dose the same and i cant find the right itunes helper!

    I now spent 15 min to register, just telling you "Thanks Avarix" for a simple and working solution :-)

  • Eaglet81 Level 1 (0 points)

    Avarix, I love you. That is the BEST solution and you made my day. One note: If you're using Win7, you must right click on the download file at the bottom (iTunes64Setup.exe) and click "show in folder." THEN right click and select "Run as Administrator." Solves the problem completely.
