Are you sure it's asking for the Product ID? During the installation process you
are asked to enter the Product Key. The Product ID can only be found after a
successful installation.
If you're installing an upgrade version, and you're performing a clean
installation, it should ask for a previous installation CD for validation.
If it hasn't ask for that, you're either installing an OEM version or a Retail
version. If it's rejecting the Product Key you're entering, either it's not the
correct one or you're entering it incorrectly.
