Hello tferratt,
You have posted your question in the beta forums (technology preview is fancy schmancy for beta).
As the beta is over and I hope you installed released version of workstation I suggest to repost your question in the actual current VMware Workstation forum here: VMware Workstation
I'll leave your question here now so that Carl can answer to your specific question. But really for maximum exposure do repost your question in the correct area.
