It would appear that you have two basic options, Nested and a 'Private' setup . . . although it's not really clear why you need this to run your analyser !

Nested: you can Nest VMware Workstation within another, but with quite a performance hit.  In your setup you could have your VMware Workstation Pro on the host, with the Ubuntu VM in which you have VMware Workstation Player installed, then create a Win 7 VM within this.  But please don't come back to this forum complaining of poor performance.

Private: The other alternative would be to setup within your current VMware Workstation Pro two VMs, one with Ubuntu and the other with Win 7, and setup with a private network connection, appropriately configured, between the two VMs.
