Getting err: failed to connect to host (22002 The specified version was not found)

I'm getting this error when I run the sample script "guestOps". What does it mean the specificed version was not found? I thnk it is referring to the VIX_API_VERSION in the VixHost_Connect() function.

1. ./guestOps "[configs] vmshe-vm-4-54/vmshe-vm-4-54.vmx"

failed to connect to host (22002 The specified version was not found)

jobHandle = VixHost_Connect(VIX_API_VERSION,          // api version

                               CONNTYPE,                 // connection type

                               HOSTNAME,                 // host name

                               HOSTPORT,                 // host port

                               USERNAME,                 // username

                               PASSWORD,                 // passwd

                               0,                        // options

                               VIX_INVALID_HANDLE,       // property list handle

                               NULL,                     // callback

                               NULL);                 

thanks,
