That registry key is internally used by Windows Installer, and that
GUID is a Windows Installer product code. You should use
<ProductSearch> instead of looking in the registry.
If the third-party program uses major upgrades, ie. changes its
product code on every version, I don't think you have any alternative
than to list all the valid productcodes...
