1. Unregister an OpenEdge installation. For each registered installation, run the setdlc script to unregister:
    • Windows: 
      setdlc.bat -unregister absolute-path-to-DLC
    • Linux: 
      setdlc -unregister absolute-path-to-DLC
  2. Remove ESAM registry entries.
    • On Windows: 
      C:\Windows\System32\openedge.d\oesec.reg
    • On Linux: 
      /etc/openedge.d/etc/openedge.d/oesec.reg
