VixVM_RunProgramInGuest vix library in python

Dears

I am new to VIX API, i wrote a new program as follow

import vix

host = vix.VixHost()

vm = host.open_vm("/home/Somebody/VM/Windows.vmx")
vm.login(username="User", password="Password")

vm.proc_run("C:\\Program Files\\Microsoft Office\\Office14\\WINWORD.EXE")

after executing the script, i found that the word application started under vmtoolsd service , so it doesn't start in user space , it runs from  service vmtoolsd and i see intractive message is prompted

How can i execute word as the user i logedin?

Thank you
