The lower-priced LabVIEW packages do not come with the ability to create standalone EXEs from LabVIEW VIs. Check under the Tools menu to see whether you have a "Build Application or Shared Library (DLL)" option. If not, you'll have to upgrade to the Professional package or purchase the Application Builder separately.
As for the run-time engine: this is freely downloadable
here and will allow you to execute LabVIEW-created EXEs on any target machine, but that won't help you unless you can use the App Builder to create EXEs in the first place.
Hope that's clear,
John
