    You must specify the UpgradeCode and increment the ProductVersion to update a product. The UpgradeCode will remain the same for newer versions.

    The UpgradeCode property indicates a family of related applications consisting of different versions and different language versions of the same product.

    This article explains the ProductCode, ProductVersion and UpgradeCode:
