Thanks for the response guys,
when I go to the Fileconect website, I got confuse between the following two files:
Filename: Symantec_Network_Access_Control_SE_12.1.1_MP1_Full_EN.exe
Version: 12.1.1 MP1
Description: Windows Base Product + Inline Update
Filename: Symantec_Network_Access_Control_SE_12.1_RU1_Full_EN.exe
Version: 12.1 RU1
Description: Multi-Platform Inline Update
which one should I download and install in order to get the SNAC enabled for my SEPM v 12.1 RU1 MP1 ?
