Mathematica Project Properties Location dialog box sets
the location of Mathematica for your project.
To access the Location dialog box, you must open the
Mathematica project properties (as shown previously)
and open the Mathematica subtree. An example of the
Location dialog box is shown below.
If you check the Override workspace setting, you can use the Mathematica installation management provided by the Workbench to choose and configure a particular installation of Mathematica to use just for this project.
