Hyper-V is pre-installed on our FRED Workstations which may interfere with the installation and operation of VMWare or Virtual Box. The reason for this is that only one software component can use the hardware at a time.

See the article at https://support.microsoft.com/en-us/help/3204980/virtualization-applications-do-not-work-together-with-hyper-v-device-g to disable Hyper-V. You should then be able to install and operate your selected VM package.
