UPGRADINGPRODUCTCODE property (Windows)

UPGRADINGPRODUCTCODE property

UPGRADINGPRODUCTCODE property

Applies to: desktop apps only

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.

Requirements

Version	Windows Installer 5.0 on Windows Server 2008 R2 or Windows 7. Windows Installer 4.0 or Windows Installer 4.5 on Windows Server 2008 or Windows Vista. Windows Installer on Windows Server 2003, Windows XP, and Windows 2000. See the Windows Installer Run-Time Requirements for information about the minimum Windows service pack that is required by a Windows Installer version.

That is massively confusing. What it is trying to say is that this property is supported by all Windows Installer versions available to date. Namely, MSI5.0 (which is only available in Win7+), MSI4.5 (available for Vista+), MSI4.0 (which is only avaible in Vista) and all MSI version built into those "older" operating systems. Ultimately, this property has been available since MSI 1.1 or so.
