 The Clarujust installer should probably check that ezFIT has been installed (by checking the path and version in the Windows registry), and then it can proceed with the installation.
 ===== Sample Script =====
-This sample script shows how to check if ezFIT (Stand-alone) is installed on the system, and if it is not, then we install it.  It also describes how to get the installation path from the Windows registry.  Please note, a similar logic needs to be implemented for the ezFIT for Noah version.
