Known issue that may occur when you try to remove Office updates

How to remove an update by using a Windows Installer command

Note These instructions do not apply to the 2007 Office suites. The Add or Remove Programs tool provides the option to remove any update that applies to the 2007 Office suites.

There are some cases where you do not have the option to remove an update when you use the Add or Remove Programs tool. This issue occurs even though the following conditions are true:

• The update was released after July 12, 2005.
• The update includes the ability to remove the update.

If this issue occurs, you can remove the update by using Windows Installer 3.1. The Windows Installer 3.1 redistributable system component will install on the following operating systems:

• Microsoft Windows 2000 Service Pack 3 (SP3) and Microsoft Windows 2000 Service Pack 4 (SP4)
• Microsoft Windows XP original release version, Microsoft Windows XP Service Pack 1 (SP1), and Windows XP SP2
• Microsoft Windows Server 2003 original release version
  
  Note Windows Server 2003 SP1 already includes Windows Installer 3.1.

  • The full_path_to_.msp_file placeholder represents the complete path of the update package (.msp file).
• The following is an explanation of the parameters for this command:
  
  The /qb switch. If you use the /qb switch, you are prompted if an update is not removable. If you use the /passive switch, you are not prompted if an update is not removable. If you use the /qb switch and if an update is not removable, you receive the following message:
  Uninstallation of the patch package is not supported.

For example, to remove an update where the product code is "{0C9840E7-7F0B-C648-10F0-4641926FE463}", and the path of the .msp file is "C:\Update\file name.msp", you would type the following in the Run dialog box:To obtain the full path of the .msp file, follow these steps:

1. Locate the .exe file that you used to install the Office update. If you do not have the file saved to the hard disk drive, download and then save the Office update to a folder on the computer.
2. Use a file extraction utility, such as WinZip, to extract the files from the .exe update file.
   
   One of the files that is extracted should be a .msp file. This is the file that you must point to when you run the command to remove the Office update.

Note Instead of the full path of the .msp file, you can also specify the patch GUID. For example, to remove an update where the product code is "{0C9840E7-7F0B-C648-10F0-4641926FE463}", and the patch GUID is "{EB8C947C-78B2-85A0-644D-86CEEF8E07C0}", you would type the following in the Run dialog box:The third-party products that this article discusses are manufactured by companies that are independent of Microsoft.
