How to retrieve Office Product Identification Code

[Marcio Ferreira]

Hi All,
I would like to know how to programmatically retrieve the Microsoft Office
"Product Identification Code" for all versions (from 97 to 2003)

I got from Microsoft KB two registry entries:
1) Office XP (Q325081):
HKEY_LOCAL_MACHINE\software\microsoft\office\10.0\registration\{90280409-600
0-11D3-8CFE-0050048383C9}
2) Office 2000 (Q217623):
HKEY_LOCAL_MACHINE\Software\Microsoft\Office\9.0\Registration\ProductID

Does anyone knows how to get the Product Identification Code from the other
versions (97 and 2003) ??

Thanks in advance,
Marcio Ferreira
