Hello John,
Thanks for your post. As I understand, you are experiencing the problem as
described in the following KB article:
PRB: "Please Enter a Valid Product Key to Use This Product" Error Message
When You Start Visual Studio .NET
http://support.microsoft.com/?id=818532
Based on my experience and research, a full uninstall and reinstall Visual
Studio .NET 2003 is necessary. FYI, I attempted to open registry and change
the HKLM\SOFTWARE\Microsoft\VisualStudio\7.1\Registrat ion "PIDkey" with a
correct product key, however, this did not change the error.
Please feel free to let me know if you have any problems or concerns.
Have a nice day!
Regards,
