Try removing SEP client using msiexec command. You need to create a small batch file with the help of following article.

To uninstall the Symantec Endpoint client using comand line 12.x:

  1. Log on the system with administrator rights.
  2. Find the Symantec Endpoint Protection uninstallation product key:
  3. Click Start, then Run.
  4. Type regedit to open the Windows reistry editor.
  5. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\
  6. Browse the Uninstall sub keys in the left-hand pane, check the values in the right-hand pane to find a value for DisplayName that is Symantec Endpoint Protection.
  7. Copy the uninstallation key.
    For example the key for Symantec Endpoint Protection 12.1.671.4971 is A3AEEA68-AC93-4F6F-8D2D-78BBF7E422B8.
  8. Click Start, then Run.
  9. Type cmd to open the Windows command prompt.
  10. At the Windows command prompt type:
    msiexec /X {product uninstall key}
    For Example: msiexec.exe /x {A3AEEA68-AC93-4F6F-8D2D-78BBF7E422B8} /passive

    To generate a detailed uninstall log type:
    msiexec /X {product uninstall key} /I*v! log file path

  • Example: msiexec /x {A3AEEA68-AC93-4F6F-8D2D-78BBF7E422B8} /lv!* c:\uninstallSEP.txt

Note: If the MSI uninstall has stopped responding:

  1. Click Start, then Run.
  2. Type taskmgr
  3. Click the Processes tab.
  4. Click End Process for all of the running windows installer processes by: Right-clicking onmsiexec.exe then clicking End Process.
