Hi Fonsi,

System Exec.vi will allow you to run commands like launching a program easily but it is difficult and many times not possible to execute commands within an application.

A better way maybe to approach this though ActiveX. 

If you are not familiar to ActiveX and LabVIEW, please read the document below:
ActiveX and LabVIEW

I hope this
helps.
