We have had at least 2 prospects run into installation problems with Higgs, due to the presence of security systems such as FoxT (BoKS):
When Higgs performs the SSH check to the master (or masters in a split install), the check fails since these systems require some additional steps to complete the SSH connection (2 factor authentication, or prompting for an RSA key, for example).
Customers have discovered that they need to disable systems such as BoKS, and then they can complete the installation as normal. We have also suggested the workaround of letting Higgs create the answer file, and then they could run the installer manually and point to that file. Assumption is that this would work as well.
