Exchange 2010 and KB 979744

    Question

  • I am installing Exchange 2010 on a new Windows Server 2008 R2 x64 instance. The exchange setup requires that several hotfixes be installed.  The Exchange Readiness Check failes with the error:

    Client Access Role Prerequisites

    Failed

    Error:

    This computer requires the update described in Microsoft Knowledge Base article 979744 (http://go.microsoft.com/fwlink/?linkid=3052&kbid=979744). Please install the required update to proceed.

     

    When I try to install the hotfix for KB 979744 I get the error "This update does not apply to your system."  I have .NET 3.5 SP1 installed.

    HELP!  Any suggestions?

  • If the server is Windows Server 2008 R2, it will not show you "Windows Sever Enterprise, Service Pack 2", if it does, reinstall!! ;)

  • Hi Eclipse,

    Install SP1 for Windows Server 2008 R2 first, the Patch KB979744 is not then longer required.

  • SP1 will not install because the OS shows as Windows Sever Enterprise, Service Pack 2.  Seems we're stuck in a loop!

  • Hello,

     

    Have you compare the system file versions according to the following KB?

    Are they newer on your computer?

     

    Thanks,

  • The files are newer on my computer.

  • Just a silly question. Is the update the x64 one for your specific OS, something like, Windows6.1-KB979744-x64?

  • Yes, the one I'm installing is Windows6.1-KB979744-v2-x64.msu

  • Hi Sherrie,

     

    I think it should be system files issue.

     

    Does this issue occur when installing the other roles on other computer?

     

    If it is convenient, a reinstall of the Windows should be the most efficient workaround solution.

     

    Thanks,

    Simon

  • If you decide to reinstall then I would go with Windows Server 2008 R2.

  • No the issue does not happen when installing other roles.

  • I'm getting to the point of reinstalling Windows...problem is the system is already Server 2008 R2.
