Unity Mode activation by a vbscript does it possible

Hi

       I want to display a application on my host computer  that is running on a virtual machine (guest). I am starting the virtual machine with this little vbscript:

     Option Explicit

     Dim WshShell, oExec

     Set WshShell = CreateObject("WScript.Shell")

     Set oExec = WshShell.Exec("C:\Program Files (x86)\VMware\VMware VIX\vmrun.exe start ""D:\Production\BEB\machine.vmx"" nogui")

     I am using the wmrun because i can start the virtual machine in nogui mode. This code work fine but not as i would like. I want to start the unity mode to be able to display my application but not the virtual machine on my host. I find some reference as adding this line the .vmx file and this is not working very well.

Does it possible to activate the unity mode with the vmrun command  ?

Thank you

Have a good day
