// To Do:  Create a custom action for this entry-point function:
// 1.  Right-click on "Custom Actions" in the Sequences/Actions view.
// 2.  Select "Custom Action Wizard" from the context menu.
// 3.  Proceed through the wizard and give the custom action a unique name.
// 4.  Select "Run InstallScript code" for the custom action type, and in
