Please help..Run Application from Command Button

[TKM]

Our work wants to impliment HD Encryption on our laptops. We would like to
put a command button on the nice instruction word document that we will be
emailing to the users. We would liek them to click on the button and it will
install automatically. The strip of code that needs to run (I think) is
something like this..
c:\programfiles\netinst\ninst32.exe",/execute:{189**********bla bla bla.

What do I need to do>
Thanks in advance
