How to: Add a File Search in the Launch Conditions Editor
The Launch Conditions Editor can be used to specify a search for a file on a target computer during installation. If the file is not found, the Property property can be evaluated for conditional installation. You can also set file search properties to specify the location of the file, or attributes such as version, size, and date.
The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Working with Settings.
