Trying to make a simple batch script to install software to users machines

Hi,

I am trying to make a simple script that will install Spark instant messenger to all my users.

Right now I have

@echo off
Net Use X: \\servername\data\it_folder\software
start \\servername\data\it_folder\software\spark.exe
@echo off

What am I missing?

I want the script to map the drive and then run the executable. If possible make it silent as well.
