Starting in Enterprise Endpoint Security E80.84 Windows Clients, it is possible to uninstall the Endpoint Security Client when it is in one of the following states:

  2. Run the following command:

    REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer" /VE /T REG_SZ /F /D "Service"

  3. Boot the machine into Safe mode (without Network).

  4. In Safe mode, open a Command line "as Administrator".

  5. Run the command: net start msiserver

  6. Wait until the following message appears: The Windows Installer service was started successfully.

  7. Go to 'Control Panel > Programs and Features'.

  8. Select 'Check Point Endpoint Security' and press 'Uninstall'.

  9. When password prompt appears, enter the Endpoint Security Client uninstallation password

  10. Follow the instructions displayed on the screen.

Note: Windows 10 (E80.62/EP6.0): Test the procedure in sk118152 first.
