The old LP plug-ins were discontinued when the new ones were added to SONAR. If you had SONAR 2016 prior to April 2016, the plug-ins are available in the Engineering FX Suite. Rolling back the Engineering FX Suite to 1.0.0.13 will install the old plug-ins. The reinstall the current Engineering FX Suite to restore the Command Center Status indicator.
If you do not have access to old Engineering FX Suite installers, running an advanced install of any version of SONAR X3 or older that included the plug-ins is the other way to get the missing plug-ins installed.
