How to: Set Installation Conditions for a File in a Deployment Project
Installation conditions allow you to specify the conditions under which a file will be installed. For example, you might have two versions of an executable file, each designed to run on a particular version of Microsoft Windows. Rather than creating a separate installer for each version, you can set the condition property for each file and include them both in a single installer.
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 Visual Studio Settings.
To set an installation condition for a file

In the Properties window, select the Condition property and enter a valid condition.
