    "An unknown Invocation Mechanism" error

    Igor Mihevc

      Hello all,

      I'm new to Truesight Orchestrator, and I'm trying to execite few basic operations using it in my test environment.
      Currently, I'm trying to execute "stop print spooler" but always get the error: "Process failed: an unknown invocation mechanism "" has been supplied"

       

      What exactly is a problem?

      In my AP I have the following adapters configured: Command line adapter, File adapter, Windows Command Adapter (target: localhost - the same machine as AP, with my administrator username and password, all other options default).

       

      I need some help and advice. Documentation is not really helpful with that error.

       

      Best regards,
