Setup Factory for Windows Installer
This tab allows you to define custom properties for your installer. These entries will be entered into the Property table of the MSI database. Properties can be used to hold information that will be used in paths, dialogs, conditions and other places in your installer.
Note that you cannot set a property to another property. You must set a property to a literal value. If you want to set a property with the value of another property, use the Set Property custom action.
Keep in mind that properties are plainly visible in the Property table, so do not use properties to store sensitive information such as passwords or serial numbers.
Most properties should be defined as public properties. Public properties can be set from outside of the installer - on the msiexec command line, for example. To define a property as public, it should be all uppercase letters. Public properties are the most accessible properties to use. Please see the links below to learn more about properties in Windows Installer.
Press the Add button to open the Property Settings dialog and create a new property.
