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.
Important This section, method, or task contains steps that tell
you how to modify the registry. However, serious problems might
occur if you modify the registry incorrectly. Therefore, make
sure that you follow these steps carefully. For added protection,
back up the registry before you modify it. Then, you can restore
the registry if a problem occurs. For more information about how
to back up and restore the registry, click the following article

and restore the registry in Windows
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.
1. Close all Office programs.
2. Click Start, click Run, type regedit, and then click OK.
3. Locate and then click the following subkey, depending on
your version of Windows and of Office:
32-bit versions
2007 Office system
HKEY_LOCAL_MACHINE
\Software\Microsoft\Office\12.0\Registration
Office 2003
HKEY_LOCAL_MACHINE
\Software\Microsoft\Office\11.0\Registration
Office XP
HKEY_LOCAL_MACHINE
\Software\Microsoft\Office\10.0\Registration
64-bit versions
2007 Office system
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\12.0\Registration
Office 2003
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\11.0\Registration
Office XP
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\10.0\Registration
4. Export the Registration subkey.
You can make a backup of the values under the Registration
subkey if the new product key does not work. To do this, follow
these steps:
1. Right-click the Registration subkey, and then click
Export.
2. In the Save in list, select a location to save the
registration entries.
3. In the File name box, type a name for the .reg file
that you want to export, and then click Save.
Note In steps 4a through 4c, you created a backup of the
Registration subkey. You can restore the Registry settings of the
Registration 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.
5. Under the Registration 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 Productname registry entry.
After you find the GUID that contains the version of your Office
program, follow these steps:
1. Right-click the DigitalProductID registry entry,
click Delete, and then click Yes.
2. Right-click the ProductID registry entry, click
Delete, and then click Yes.

correct GUID for the version of the Office suite or program that
you have installed on your computer, click the following article
