Exchange 2010 and KB 979744


  • 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



    This computer requires the update described in Microsoft Knowledge Base article 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!! ;)
