According to their response it seems they want me to make the launcher:
"I did see that the Tisnart games were built with this engine, and used the workaround method you described. It should work for Plantera as well. Just as he described, you will need to create the launcher .exe that we will apply our DRM to. It must have these requirements:
- A launcher.exe file will run the game.exe. This is the file that will be protected by the DRM (Armadillo).
- This launcher.exe and game.exe are dependent on each other. When the DRM stops launcher.exe, the main executable (_____.exe) will also be stopped. It should work the other way too. When the main executable is stopped, the launcher is stopped.
- And last, make sure the main executable can't be launch by double-clicking it. That's why we have the launcher.exe (made without .NET). This will prevent people from bypassing the DRM.
I hope all goes well with this method. If you have any other questions or concerns, let me know."
