e-Licenser Control Center

I NEED HELP I was just using Nexus and I woke up this morning And the e Licenser control center says it cannot start the Sysnopos.app file and I can no longer access my work I uninstalled and tried to update the control center and now the control center won’t install saying there is an instance of the program running and there is clearly NO instance of the program running

Did you restart your computer before installing the control center again?
