322756 How to back up and restore the registry in Windows XP and Windows Vista



SYMPTOMS
You cannot change the product key for Microsoft Office XP, for Microsoft Office 2003, or for the 2007 Microsoft Office system without first removing and then reinstalling Microsoft Office.



RESOLUTION
To resolve this issue, follow the steps in this section.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

Note If you try to open any Office programs after you complete the steps, you receive a message that prompts you for a valid product key. Make sure that you have a valid product key before you start these steps.  Close all Office programs. Click Start, click Run, type regedit, and then click OK. Locate and then click the following subkey, depending on your version of Windows and of Office:

32-bit versions

2007 Office system

Office 2003

Office XP

64-bit versions

2007 Office system

Office 2003

Office XP

 Export the  subkey.

You can make a backup of the values under the  subkey if the new product key does not work. To do this, follow these steps:  Right-click the  subkey, and then click Export. In the Save in list, select a location to save the registration entries. In the File name box, type a name for the .reg file that you want to export, and then click Save.</li></ol>

Note In steps 4a through 4c, you created a backup of the  subkey. You can restore the Registry settings of the  subkey by double-clicking the .reg file that you saved in step 4c. The contents of the .reg file are automatically exported to the Registry.</li> Under the  subkey, there may be several Globally Unique Identifiers (GUID) that contain a combination of alphanumeric characters. Each GUID is specific to a program that is installed on your computer.

Click a GUID. Then, view the version of Office that is listed in the right pane for the  registry entry. After you find the GUID that contains the version of your Office program, follow these steps: <ol style="list-style-type: lower-alpha;"> Right-click the  registry entry, click Delete, and then click Yes.</li> Right-click the  registry entry, click Delete, and then click Yes.
