Can't get this particular cmd code to work in WPI

[illusions]

Hi I have this remove.cmd batch

 

echo.
echo ** select the printer driver to be remove
echo.   

rundll32 printui.dll,PrintUIEntry /s /t2
pause

 

 

 

When I double click remove.cmd at windows 7 explorer

The "Print Server Properties" windows will open to allow me to select which driver to delete.

 

 

But when I use wpi to execute remove.cmd

nothing happen

The "Print Server Properties" windows will not open

 

Please advice.
