The Path Variables Editor

Path Variables are used to specify locations on the file system. The location of the project resources may be specified relative to these path variables. In this manner you can avoid references to a hard-coded location on your file system which are very hard to maintain.

With the use of path variables, you can configure your project so it can be moved from one computer to another painless, without requiring the exact same directory structure as on your file system. All you have to do is make sure that the path variables are defined on both systems.

Path variables are used during the development of your installation project. They do not apply to the target computers where the package is installed. Thus they cannot be used instead of formatted references.

To convert the existing absolute paths to path variables use the Convert Paths wizard ( "Project" -> "Convert Paths..."). This wizard scans your installation project for static paths and changes them to path variables, which makes your project more easily portable. Alternatively the wizard allows you to transform project paths that already use path variables, to absolute.

Creating a new path variable

Use the [ New... ] button, the "New..." context menu option or press the Insert key.

Editing a path variable

Use the [ Edit... ] button, the "Edit..." context menu option or press the Space key.

Deleting a path variable

Use the [ Remove ] button, the "Remove" context menu option or press the Delete key.

Path variables are global. This means that they are shared across different projects. Editing or removing ore may destroy those projects.
