The KeyPath attribute is set to yes to tell the Windows Installer that this particular file should be used to determine whether the component is installed. The Source attribute specifies the location of the file on your machine, so WiX can find it and build it into the installer. The Id is used to refer to the file elsewhere in the WiX project. For information on generating GUIDs see How To: Generate a GUID.īeneath each component is a File element that does the actual work of packaging your source files into the installer. The Guid is used later for patches and must be unique for each component. The Id is used to refer to the component later in the WiX project. Each Component element is given an Id and a Guid. This is in keeping with the best practice of having one component per file. Underneath the DirectoryRef are two Component elements, one for each of the two files that will be installed. By referencing the APPLICATIONROOTDIRECTORY directory, the files will be installed into the c:\program files\My Application Name folder. The DirectoryRef element is used to refer to the directory structure created in step 1. The following sample uses the directory structure defined in Step 1 to install two files: an application executable and a documentation file. Failure to follow these two basic rules can lead to many problems down the road when it comes to servicing. Every component must have its own unique GUID. The Windows Installer is designed to support thousands of components in a single installer, so unless you have a very good reason, keep to one file per component. In general, you should restrict yourself to a single file per component. While it may not seem like a big deal when you are first authoring your installer, components play a critical role when you decide to build patches at a later date. This is separate from whether the set of items consist of a logical feature the user can select to install which is discussed in Step 3. The component element describes a set of resources (usually files, registry entries, and shortcuts) that need to be installed as a single unit. Step 2: Add files to your installer package Ī file is added to the installer using two elements: a Component element to specify an atomic unit of installation and a File element to specify the file that should be installed. The result of these tags is a c:\Program Files\My Application Name folder on the target machine. The id is in all capital letters to make it a public property that can be set from UI or via the command line. The third directory element creates your application's folder under Program Files, and it is given the id APPLICATIONROOTDIRECTORY for later use in the WiX project. In most cases this will resolve to c:\Program Files\. The second element, with the id ProgramFilesFolder, uses a pre-defined Windows Installer property to reference the Program Files folder on the user's machine. Every WiX project will have this directory element. The element with the id TARGETDIR is required by the Windows Installer and is the root of all directory structures for your installation.
