MS Office Administrative Install Points and Microsoft Update and WSUS update supportThe information in this article applies to: SYMPTOMSNo Microsoft Office updates are displayed when using Microsoft Update or Microsoft Windows Software Update Services (WSUS) and the client computer is configured to use a Microsoft Office administrative installation point as a installation source. However, the same client computer may show available Office updates if the Office Update Web site is used. (Note: the Office Update Web site informs you that one of more of the updates cannot be installed because Office was first installed from an updated administrative installation point.) CAUSEThis behavior occurs if a client machine uses an updated Office administrative installation point as the installation source. Updates can only be properly detected by Microsoft Update or by WSUS if they have been applied directly to a client machine and not to an administrative installation point. WORKAROUNDTo work around this issue, use of the following methods: Method One Revert the updated administrative installation point to an unaltered installation source. Method Two Continue to update Office clients by patching the administrative installation point.

How To: Switch Microsoft Office to use an original baseline sourceSUMMARYThis document describes the process for switching the source for a client machine to a Microsoft Office original baseline source (OBS) from an updated administrative installation point (AIP). A popular method of deploying and maintaining Microsoft Office is through the use of an AIP. In this scenario, patching the AIP and executing a recaching reinstall Office on the clients is usually the most efficient patching strategy. The recaching reinstall replaces the previously cached MSI file on users' computers and overwrites any old files with the newer versions. New clients that install from the patched administrative image automatically get the updated version — you do not need to chain patches to the core installation. However, if an administrator wishes to use Microsoft Update (MU) or the Windows Software Update Services (WSUS), the AIP must be an OBS without any updates or hotfixes applied. In most scenarios, it is not necessary to completely uninstall Microsoft Office to switch the client to a fresh installation from an original baseline source. NOTE: You must uninstall the current installation and deploy a fresh install from an OBS if:
o The client machines have a version of Windows Installer greater than or equal to 3.0 o The client machines have one or more client side Office updates currently installed o The current AIP has a Service Pack installed
Switching to an OBS only requires a few steps. Step One: Create an OBSAn OBS is either a copy of the original compressed media or an AIP built from the original compressed media with no other updates applied.
NOTE: If you will be updating all client machines to the OBS at the same time, you can replace the existing source with the OBS in the same location; otherwise, the recommended method is to create a new location for the OBS (leaving the existing source intact) to allow switching the clients in stages. Step Two: Execute a recaching reinstallAlthough it may be feasible to recache the client with the OBS and deploy a client side Service Pack (SP) separately, it is more efficient, and frequently necessary, to apply the client side Service Pack during the recaching reinstall. To do so one would execute a command line like the following: MSIEXEC.EXE /I <Path to OBS>\<filename>.msi REINSTALLMODE=VOMU PATCH=<Path to SP>\<filename>.msp If the Office installation is managed through an AD Software Deployment you should not use the command line method to execute a recaching reinstall. Instead redeploy the package and then use WSUS to distribute the Service Pack. Step Three: Update the client machine with additional Office updatesThe distribution of all updates that were previously part of the updated AIP should be expedited to ensure that the proper versions of replacement files are used if any repair is needed. You can now use WSUS to distribute these and any additional Office updates, Optional: If you are using Office 2003 it is recommended that you also implement a Local Installation Source (LIS). This can be accomplished with the LISTool.
