Are you looking for the MSI file for the update? If so, what version of the HP Media Server are you running?
Sir,
I found the MSI file plus detailed instructions for installation (http://www.mediasmartserver.net/wiki/index.php/Installing_the_HP_MediaSmart_Server_2.5_Update_on_the_EX47x)
This is for the HP Media Smart Server ES47x, and ES48x.
Hope this helps.
