For installer files, the Keywords property should take the form: Installer.ProductName.OptionalInfo, where ProductName is the name of the application to be installed, and OptionalInfo contains optional information such as a version number.
Remarks
The Keywords property is displayed on the Summary page of the Properties dialog box when an installer file (.msi) is selected in Windows Explorer.
