Hello Dino,
Installation of VMWare tools was initially planned to be installed automatically, but there were concerns with the security implications of having them installed. As such, they were not included by default, and, as you say, there is no GUI for the installation.
In addition, there is no ability to install using the SPC_Admin account as you do not have command line access.
In testing the tools have been installed successfully by launching the setup at the command line, but again, because of the security concerns around the file sharing and the other holes this makes in the security of this SECURITY APPLIANCE, support for this has not been included.
