I was away for a demo the other week and the night before I tried to launch the demo VM to do some final preparation when I got the following error:
GP Demo - VMware Workstation>/p>
Not enough physical memory is available to power on this virtual machine with its configured settings.
This error message was a baffling one as I had run the VM a couple of days previously with no problems and had made no changes to the laptop in the intervening period.
The fix was a rather odd, yet simple one: launching VMware Workstation using Run as Administrator allowed the application to launch and the VM work without further problem.
Since doing this I have been able to launch the VM at any time under my usual security context.
