Microsoft Service Pack Uninstall Tool for Office 2010


Applies to: Office 2010

Topic Last Modified: 2011-08-04

The Microsoft Service Pack Uninstall Tool for the Office 2010 suites (or Office 2010 SP1 Uninstall Tool) allows administrators or advanced users to remove Service Pack 1 (SP1) for Office client products without uninstalling the complete product. This command line tool is included in Microsoft Office 2010 SP1. You can also uninstall Microsoft Office 2010 SP1 directly from Control Panel through Add or Remove Programs or Programs and Features.

In this article:

The 2010 SP Uninstall Tool is contained in a package called Office2010SPUninstall.exe, which is a self-extracting executable file. The tool itself is a single file that is named OARPMan.exe. No installation is required for the tool. The OARPMan.exe file, the Microsoft Software License Terms (previously known as End User Licensing Agreement or EULA), and the Readme.txt files are extracted to the location that users specify. Download the tool at The Microsoft Service Pack Uninstall Tool for Office 2010 (http://go.microsoft.com/fwlink/p/?LinkId=225562)

A release is a collection of updates. In this case, the release is Office 2010 SP1. The uninstall tool removes all updates that are in a specific release. It does not uninstall per update or per product. For example, if you have Microsoft Visio 2010 SP1, Microsoft SharePoint Designer 2010 SP1, and Office 2010 Professional SP1 installed on a computer, the tool uninstalls SP1 from all these products because they are part of the same release. Due to the complexity of shared files and shared Windows Installer packages (MSI files), there is no current support for per-product service pack uninstalls.

The Office 2010 SP Uninstall Tool provides the following capabilities:

  • Uninstalls client updates only. It does not uninstall server updates.

  • Uninstalls Office 2010 Service Pack updates only. It does not uninstall Office 2007 Service Pack updates. To uninstall the Office 2007 Service Pack, download the tool at The Microsoft Service Pack Uninstall Tool for the 2007 Microsoft Office Suite (http://go.microsoft.com/fwlink/p/?LinkId=144518).

  • When Office 2010 SP1 is removed, the user's computer returns to its previous state.

    For example, if you deploy the release version of Office 2010 plus security updates, hotfixes, and Office 2010 SP1, and then you uninstall Office 2010 SP1, the user's computer is returned to Office 2010 plus security updates and hotfixes.

OARPMan.exe supports the following commands:

OARPMan /remove <release> [/log <folder path>]

OARPMan /report [/log <folder path>]

OARPMan /?

OARPMan /help


Option Description

/remove <release>

Removes from the system all updates that are marked with the specified release designation, such as “O14SP1.” If the release parameter is not specified, Help is displayed.


Reports the list of installed updates that meet these conditions:

  • The update is marked as removable (AllowRemoval = 1).

  • The update contains a value for Release metadata property.

The report contains the following items in this order:

  • Release Value

  • Product Codes

  • Update Codes

Use the /log switch together with the /report option to obtain additional log file information that is not shown in the console window.

The /report switch displays only updates that are part of releases that the tool can uninstall. It does not display other updates that are applied to Office 2010 because SP 1 is the only release that has uninstall enabled.

/log <folder path>

Creates a log for the OARPMan tool and copies the resulting MSI log files to the specified path. The <folder path> parameter is required and the specified folder path must already exist.

The OARPMan log includes success and failure messages, OARPMan errors, MSI errors, basically any information that is displayed in the console window. If the <folder path> parameter is not specified, Help is displayed.

Use the /log switch together with either the /report or /remove switches to obtain additional log file information that is not displayed in the console window.

When you use logging via the /log switch together with /remove during the uninstallation process, the MSI logs are automatically copied into the same directory as the tool’s log.
