WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.
 
For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT or Windows 2000, you should also update your Emergency Repair Disk (ERD).
 
To resolve this problem, follow these steps:
  1.. Locate your valid product CD Key (located on the back of the CD jewel case. If the product CD Key begins with GC6J3, please stop here and contact Microsoft Technical Support.
 
 
  2.. On the Start menu, click Run.
 
 
  3.. In the Open box, type regedit, and then click OK.
 
 
  4.. In Registry Editor, find the following subkey (folder):
    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall   Click the plus sign (+) next to this folder. If you see only one subkey in this folder that has a 32-character {GUID} (globally unique identifier), select that subkey and go to step 5.
 
  If you see more than one subkey that has a 32-character {GUID}, select each one until you find the one whose DisplayName value (in the right pane) matches your version of Office.
 
  For example, if you have Office 2000 Premium CD 1 and CD 2 installed, the 32-character {GUID} and the DisplayName value are:
  Office 2000 Premium CD 1
{GUID}:        {00000409-78E1-11D2-B60F-006097C998E7}
DisplayName:    Microsoft Office 2000 Premium
  Office 2000 Premium CD 2
{GUID}:        {00040409-78E1-11D2-B60F-006097C998E7}
DisplayName:    Microsoft Office 2000 Disc 2
 
 
 
  5.. For the selected {GUID} subkey, select the ProductID string value in the right pane.
 
 
  6.. On the Edit menu, click Rename.
 
 
  7.. Type OldProductID and then press ENTER.
 
 
  8.. On the Registry menu, click Exit.
 
 
  9.. Start any Office program.
