    Hello dude,
    These type of errors indicate windows Installer encountered a problem. while installing updates,
    i) Windows Update
    ii) Microsoft Update

    Solution:
    1) you should Defrag your hard drive.
    2) Clean up your disk by registry cleaners.
    3) Install good antivirus and scan your computer.
    4) You should not have two firewalls installed at the same time.

    Install Update:

    While installing update do the following steps.

    1) Turn off User Account Control settings
    Control panel -> All Control panel Items -> User Accounts
    2) Temporarily disable your antivirus.
    3) If you get error at automatic update try to manual update.

    Good Luck,
    Regards,
