Great! It says “standalone application”, with a deployment such that the (third party) user does not need a Mathematica license (at least that's my understanding). So, the crucial question is: How do I deploy the compilation, or what exactly do I need to deploy? It can't be the exe file itself (only about 160 KB in size), can it? Which “package” do I have to compile in order to make it available to third parties in an executable form? Thank you very much!
