How to check subscription days left in Symantec Endpoint Protection

Respected,

I had downloaded Symantec Endpoint Protection named: Symantec_Endpoint_Protection_12.1.2_MP1_Win32-bit_Client_EN

from symantec fileconnect by entering My product Serial Number which starts with M.

I checked my Symantec Endpoint Protection GUI/ Screen 2-3 times. I clicked each and every link on Endpoint client but not getting how many days SEP left.

I also checked .sif file but it also don't include this info.

please help in in retrieving my subscription days.

Do Symantec Endpoint Protection is for life time use or for some years only. Please specify.

Thanks

Adam
