Microsoft says the Product Code should identify a particular release (http://msdn.microsoft.com/en-gb/library/windows/desktop/aa370854(v=vs.85).aspx): "The ProductCode property is a unique identifier for the particular product release, represented as a string GUID, for example "{12345678-1234-1234-1234-123456789012}"." That seems to imply it shouldn't be changed from one build to the next but only when the major, minor or revision fields are changed. -- Bruce Cran ------------------------------------------------------------------------------ Everyone hates slow websites.
