You can run any application from a specified location using a SystemUtil.Run statement. 

"SystemUtil.Run" is especially useful if your test includes more than one application. 

You can specify an application and pass any supported parameters, or you can specify a file name and the associated application starts with the specified file open. 

for e.g. SystemUtil.run "iexplore.exe", "www.gmail.com"


"InvokeApplication" invokes an executable application.
