    ORA-12557: TNS:protocol adapter not loadable when access Designer

    383642
      I'm getting a ORA-12557: TNS:protocol adapter not loadable when trying to login to any component of Designer e.g. RAU. I have a local db installed and wondering if this might have to do with the Microsoft Loopback Adapter that had to be installed for the 10g database.
