I strongly suspect the "Click here for support information" is an option with the microsoft installer or MSI. Although LabVIEW uses the MSI for its executables, this functionality is not exposed.
I have tried several times in the past to edit a MSI and it is nontrivial. There are software packages for sale that can help make this easier. As a workaround, you might consider adding a dynamic VI to your application called About.vi . This way if you go help >> about , your VI will pop up with any information you want it to show.
