We are doing the same i.e develop GUI with rapidapp and draw in Performer
window in a separate process. Works fine. But, to run this GUI, I think
the host machine has to have the rapid app license. I developed my GUI on
Impact where I had license for rapid app and tried to run the same on an
Indy with out Rapid app license. I see only my Performer Window but not
the GUI.
Is it that, always the end user has to have the rapid app license to use
the application?
Thanks ..
