High Availability Service missing


I accidentally installed the HA installer on primary server and then uninstalled it. After Uninstalling i lost the options "High availability deployment summary" and "High Availability settings" on web console. I also cannot find the HA service in "services.msc".

Is there a way to get this service back? 

Do i need to reinstall NPM or can i use any installation file in "C:\ProgramData\Solarwinds\Installers" that can enable this options back for me.

Please advice.
