Hello,

My situation is as following, running ESX 5.5 and have created a windows 7 workstation, 64bit guest os.  I want to install VM Workstation on the Win 7 guest OS but receive the unable to power on message.  I've seen lots of different posts on how to resolve.  I have downloaded the .vmx file to my desktop and edited it in notepad.  What lines do I need to add to it and where exactly are they added?  At the end of the config file or throughout?  Also, do I need to register the vmx file?  Please help!

You need to create a nested VM, and pass-through Hardware Intel-VT.

vhv.enable = "true" at the end of the VMX file.

but make sure the VM is unregistered, and then alter the VMX file, and then Re-register the VM.

see this Article, which shows how to enable a Virtual Machine version 10, and enable hardware virtualisation passthrough

Please note, note all processors in the HOST support this.

e.g. Dell 2950 do not work, but Dell R710 and R720 do.
