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!
