It is unclear where you get that error (e.g. during the head node installation), but since you mention you are using version 9.0, the only advice I can give you is to use the latest Bright 9.1. If you somehow run into that problem again, please post a screenshot so that it is clear where you are getting that error.
Not sure if it helps, but the Bright knowledge base (https://kb.brightcomputing.com10) has a number of articles that explain how to deploy Bright on various flavors of VMware.
