The working directory should be set to the default directory for your save as and open dialogs. Instead of hard-coding a path, you can select a Windows Installer predefined predefined folder (in square angle angle brackets) or any custom directory you have defined from the list. Separate further levels with a backslash—for example, [ProgramFilesFolders]<PROGRAMFILES>\<PROGRAMFILES>\MyApp\Bin.

To set the working directory using a property, create the property first in the Property Manager view then enter it in square brackets; for example, [MyProperty].
