Hello,   Thank you.  A new package is being built.  In the meantime, you can try the setup.pl from v1.3..   Or use on of the alternative methods of installing it.    Feel free to open a support case on this as well.   They can add you into the open issue with engineering.   Regards,  Don       
The new Dell EqualLogic Multipathing Extension Module v1.4 is missing setup.pl script.
