On a system where you have installed the SEP client and the SCSP agent, if you upgrade the SEP client to version 14RU1, it breaks the functionality of the SCSP agent.
Agent drivers are not loaded and IPS feature is not working:
C:\Users\Administrator>sc query sisipsdriver
[SC] EnumQueryServicesStatus:OpenService FAILED 1068: The specified service does not exist as an installed service.
During the SEP upgrade to version 14RU1, some registry entries belonging to SCSP are removed.
