VMware Workstation Unrecoverable Error: (vmx) NOT_IMPLEMENTED

I RDP’d to my workstation and attempted to start a virtual machine in VMware Workstation 6.5.2. However, part of the way through the boot process VMware would pop up the following error:

VMware Workstation Unrecoverable Error

VMware Workstation Unrecoverable Error

Looking at the log file I would see

NOT_IMPLEMENTED d:/build/ob/bora-156735/bora/vmx/main/pollVMX.c:3651

It didn’t matter whether I was trying to start a Windows or a Linux virtual machine, I still got the error.

The cause appears to have been my display settings. I changed my RDP client settings to “High Color (16 bit)” and everything started working.

Edited at 13/8/2009:

This happened again and changing the colours made no difference. Normally I run RDP in full screen mode. I “umaximised” it and was then able to start the VM.

    This exact error happens to me with VMWare Workstation running on Windows 7.

    It’s got an easy fix – you must run VMWare Workstation as administrator (right-click / run as administrator) to avoid this error.
