    I started to update some of our Administrative workstations that run Windows
    XP Pro to Service Pack 2 and receive the below listed error on all of them
    when trying to add and remove a program. Also some programs would not run,
    one of which is IBM Client Access Express.

    "The Windows Installer Service could not be accessed. This can occur if you
    are running in Windows safe mode, or if the Windows Installer is not
    correctly installed. Contact your support personnel for assistance."

    I corrected this problem on most of the workstations by using the System
    Restore and removing the Microsoft Antispyware and shutting down McAfee and
    reinstalling the Service Pack 2 and all updates, then restart McAfee and
    install Antispyware.

    I have one workstation that came with Service Pack 2 already installed and I
    cannot restore to a date that will correct this one. Should I try installing
    the Windows Installer Redistributables 3.1 V2?

  2. Suggestion:
    To unregister and re-register Windows Installer:
    Click Start, and then click Run.
    Type in the Open box: msiexec /unregister and then click OK.
    Click Start, and then click Run.
    Type in the Open box: msiexec /regserver click OK.
    This will not affect programs which use Windows Installer that are already installed.

    If not reinstall
    Windows Installer 3.1 Redistributable (v2)

    TaurArian,

    I did try to re-register yesterday and it did not work on any of the
    workstations. I tried to reinstall the Windows Installer 3.1 Redistributable
    (v2) and it did not work. I checked the Msi.dll and it was already at
    3.1.4000.2435. I did however do a System Restore prior to SP2 and then
    deleted MS Antispyware and stopped service on McAfee. I then reinstalled SP2
    and all updates, then I reinstalled MS Antispyware and reactivated the
    services for McAfee. This is a long method but it does correct the problem.

    Thank you
    Frank
