    You posted this question in the Xserve forum where few will see it.

    Try b noir's solution here: Please help me with this error: "Apple application support was not found... Error 2"

    Apologies for posting on Xserve.  None of the forced choice options seemed to be appropriate ...



    Anyway, back to the problem.  Followed B noir's solution.  Failed!!!


    Error message is the same as when iTunes loads (albeit it says successfully).....  Message is


    An error occurred during the installation of assembly 'Microsoft.VC80.CRT,type="win32",version="8.0.50727.6195",publicKeyToken="1fc8b 3b9a1e18e3b",process orArchitecture="x86"'. Please refer to Help and Support for more infromation. HRESULT:0x8007054F.


    Hope that you can decipher this and point me in the right direction.

    Unfortunately I have seen that before, and the only reliable solution I have found on both this site and Windows support sites seems to be to reinstall Windows.


    Short of that, you can read through this post to see if the removal and reinstallation of iTunes will fix it, but in that case it did not. I believe the problem was a corrupt Windows installation and that may be what you are facing.


    Try the complete iTunes removal / reinstallation technique described in that thread first. It appears long and tedious but it takes longer to read it than to do it.

    Have tried both reinstalling Windows.  Uninstalled and Reinstalled iTunes (have also tried using Revo Uninistall recommended in other posts).  Still back to square one.  Also thought it may be a 32 bit versus 64 bit inconsistency, but havve made sure I hae downloaded 32 bit version of iTues (formy 32 bit Windows system).


    Anyone else willing to take a punt on providing a solution.....

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


    Hi Redgilly (and others).

    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.

    I hope this helps.

    Found an easy solution to this problem!  At least for Windows 7 users.  Install QuickTime from Apple.com.  This will automatically install Apple Software Update and put it on your All Programs list.  Open Apple Software Update.  It will list iTunes as a program you can download.  Check the box and download.  When I did it this way everything loaded and installed with no problems!  The Apple Application Support that the Error 2 message refers to must be in the the QuickTime insatllation.  Hope this will work for everyone else.
