    scrrun.dll might be unregistered. Re-register it then retry. This installer uses it for part of the install process.

    regsvr32 /s scrrun.dll

    How do I re-register scrrun.dll?

    I think I figured out how to register scrrun.dll. I typed "cmd" at the run
    command (in the Start menu), then registered scrrun.dll by typing "regsvr32
    %windir%\system32\scrrun.dll". I got a verification message (dialog box). I
    ran the security update again for KB979906 and it failed again for about the
    25th time. I still need help.

  5. Are you installing via Windows Update?

    Have you tried downloading KB979906 from the Microsoft Download Center and
    installing it while booted to Safe Mode?
