As far as I'm aware there is no official way to automatically deploy a SAS 9.4 PC licence on multiple computers.
However there is a possible back-door method you could try to see if it works for you. When you renew the SAS licence manually:
http://support.sas.com/kb/49/679.html
It updates a SAS catalog file called CORE.SAS7BCAT. You will find this file in a sub-folder of where SAS is installed like
C:\Program Files\SASHome\SASFoundation\9.4\core\sashelp.
If you apply the licence manually on one computer then copy the updated CORE.SAS7BCAT file to another PC (to the same folder) where the licence needs to be renewed, then it should renew it successfully.
It should be possible to script this process to roll it out over multiple computers using tools like SCCM.
