Note: If you are trying to run one of our applications then the software needs to be licensed on that machine. Also Note: You are responsible for not installing the software on more machines than you have licences; you have a single licence.
Sorry but if you want more effective help please try to be more precise with your answers.
Are you saying you have written a program that calls our .net assemblies directly in code? If so, you need to buy a toolkit license to be entitled to do that development. And a runtime license for each machine that runs your program.
