Method 1: Use a Clean Boot Installation

A clean boot is a way to create a clean environment. When you start your computer with a clean boot, Microsoft Windows starts and loads only basic devices and services. For information about how to use a clean boot and how to use a normal startup, see the "More Information" section later in this article.

NOTE: Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.

1.	Click Start, and then click Run.
2.	In the Run dialog box, type msconfig, and then click OK.
3.	In the System Configuration Utility dialog box, click Selective startup, and then click to clear all files (System.ini, Win.ini, System Services, and Startup Items).
4.	Click the Services tab, and make sure that Windows Installer is checked.
5.	In the System Configuration Utility dialog box, click OK. When you are prompted to restart your computer, click OK.
6.	Install Office XP Media Content.
7.	Click Start, and then click Run.
8.	In the Open box, type msconfig, and then click OK.
9.	In the System Configuration Utility dialog box, click to select Normal Startup - load all device drivers and services, and then click OK.
10.	Restart your computer.

Method 2: Modify the Registry

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

1.	Right-click Start, and then click Explore.
2.	Locate and right-click the Mediacntcd1 folder, click Rename, type Mediacntcd1.old, and then press ENTER. By default, the path to this folder is C:\Program Files\Microsoft Office\Mediacntcd1. This folder may not exist on your computer.
3.	Click Start, and then click Run.
4.	In the Run dialog box, type command, and then click OK.
5.	Type the following command line: msizap.exe TAWG! {90300409-6000-11D3-8CFE-0050048383C9}
6.	At the command prompt, type exit, and then press ENTER.
7.	Click Start, and then click Run.
8.	In the Open box, type regedit, and then click OK.
9.	Make sure the following subkeys no longer exist: HKEY_CLASSES_ROOT\Installer\Products\9040030900063D11C8EF00054038389C HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\10.0\Clip Organizer\Catalogs\cntcd1 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{9030040 09-6000-11D3-8CFE-0050048383C9} If any of these subkeys remains, click the subkey, click File, and then click Export. Select a safe location to which to export the subkey for recovery purposes, and then delete the key from the registry.
10.	Close Registry Editor.
11.	Insert the Office XP Media Content CD in your CD-ROM or DVD-ROM drive. Hold down the SHIFT key to prevent the program from starting automatically. If Windows Installer starts automatically, click Cancel.
12.	Click Start, and then click Run.
13.	In the Open box, type msiexec.exe /i drive:\CAG.MSI ADDLOCAL=ALL /qb /l*v! drive:\CAG.TXT where drive is the drive that contains the Office XP Media Content CD. NOTE: When you type the command, include the spaces, as shown.
