  • Installing Vista SP2 gives error hr=0x800f0a0c

    Posted on March 12th, 2009 By Andreas Stenhall + No comments

    For the last couple of days I have been assisting one the users in my Windows Community alltomxp.se (in Swedish) with troubleshooting the installation of Windows Vista Service Pack 2. The user just get “one or more system components that the service pack requires are missing. For more information, click the link below.”  The links leads unfortunately not to a page with any information on what is wrong.

    In the CBS.log the following information can be found:

    2009-03-11 20:43:11, Info                  CBS    SPI: Starting SP Compatibility\Applicability scan
    2009-03-11 20:43:11, Error                 CBS    SPI: (CSPInstall::CompatibilityApplicabilityScan:993)Detected missing components, aborting SP install hr=0x800f0a0c
    2009-03-11 20:43:11, Info                  CBS    SPI: Ending Compatibility\Applicability scan
    2009-03-11 20:43:11, Error                 CBS    SPI: (PerformSPInstallation:764)Failed to install SP using UI hr=0x800f0a0c

    The problem is that components are missing, most likely because the application vLite has been used to customize the installation. This can be verified by looking if the registry key HKEY_LOCAL_MACHINE\SOFTWARE\vLite exist and then delete it. After that the installation of Windows Vista Service Pack 2 should proceed, hopefully without further problems.
