If SEP 11.x is the product for which you are looking for then open the DVD for the SEP 11.x and then either go to SEP folder OR SEPM folder and look for "lusetup.exe"

Find it on Symantec FTP site: ftp://ftp.symantec.com/public/english_us_canada/liveupdate/3.3.0/

Secondly, In case for SEP 12.1, you can check this Article:

Hi Pat,

What's the version of SEP that you ar etrying to update, and it is the SEP client or SEPM? If it is the SEPM or a SEP 11 client, then use the client that can be downloaded from this article:
