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

How to remove an update by using a Windows Installer command
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.

Command syntax
With Windows Installer 3.1, you can remove an update by typing a		  command in the 
Run dialog box. For example, to remove an		  update, click 
Start, click 
Run, type the		  following command in the 
Open box, and then click		  
OK:
 msiexec /package {product_code} /uninstall "full_path_to_.msp_file" /qb
 NotesFor 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:
 msiexec /package {0C9840E7-7F0B-C648-10F0-4641926FE463} /uninstall "c:\update\file name.msp" /qb
To obtain the full path of the .msp file, follow these steps:		  
- 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.
 -  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:
 msiexec /package {0C9840E7-7F0B-C648-10F0-4641926FE463} /uninstall {EB8C947C-78B2-85A0-644D-86CEEF8E07C0} /qb
