I'm getting the following message when attempting to boot into an OS X Lion guest:
Could not get vmx86 version: The handle is invalid.
You have an incorrect version of the driver "vmx86.sys".
Try reinstalling VMware Workstation.
Failed to initialize monitor device.
I'm running Windows 7 Professional x64
(The steps I took are as follows:
- downloaded and extracted unlock-wks800-471780-windows.zip
- ran cmd.exe
as an Administrator and navigated to the extracted folder
- ran install.cmd)
EDIT: I found a workaround. Run VMware Workstation as an administrator and the problem goes away. This problem occurred for all my guests, not just OS X.
