I am trying to run IDL code via Labview 7.1. I have a licence for IDL6.1 but when I am trying to run my vi containing the IDL node I have an error message error sayinf that I need a IDL development licence and a IDL Labview script node licence (idl_lvsn). I thought that you only to have a valid licence for IDL, do I have to buy a specific licence to use the IDL Labview script node?
