Register todayUPGRADINGPRODUCTCODE property
The UPGRADINGPRODUCTCODE property is set by Windows Installer when an upgrade removes an application. The installer sets this property when it runs the RemoveExistingProducts action. This property is not set by removing an application using the Add or Remove Programs in Control Panel. An application determines whether it is being removed by an upgrade or the Add or Remove Programs by checking UPGRADINGPRODUCTCODE.
