Hi Kurt,
as far as I know, this is a consequence of the fact that all SAS Solution have the option to integrate SAS VAAR (Visual Analytics - Administration and Reporting).
Hence, the SAS 9.X deployments will include the SAS Visual Analytics Services and SAS Visual Analytics Administrator, for integration purposes in case VAAR will be included afterwards.
Also, I think it is included when you install with a custom plan file, but not sure if it comes with the pre-created plan files. I would need to check that.
