Which MSI UpgradeCode, ProductCode, and PackageCode does think-cell use?
The UpgradeCode, ProductCode, and PackageCode are unique identifiers (GUIDs) that identify a product release.
The UpgradeCode identifies all program versions and is therefore always the same:

All other codes like ProductCode and PackageCode change with every build.
