System Center Endpoint Protection (SPEC) may not install via SCCM policy if a conflicting application exists and cannot be uninstalled. This is commonly associated with an existing Antivirus application.
In order to find what the conflict is;
- Open regedit
- Navigate to \HKLM\SOFTWARE\Microsoft\CCM\EPAgent
- Look at “StateEventMessage” where you will find a message similar to the below:
In this example, the Trend Micro OfficeScan Client was installed and for whatever reason, SCEP could not remove it. At this point you will need to manually remove the conflicting application and re-initiate a policy refresh to the SCCM server.
Navigate to Control Panel, open the Configuration Manager client, clicked on the Actions tab, and force each action to run.
After a while the new SCEP icon will appears as expected.
