JavaFX .exe file created with Ant Failed - javafx

Question

I am developing an JavaFX application and used the native packaging tool (incl. Inno Setup 5 and WiX) to create .exe files and installers. The program is a self-containing application. When I install and execute it on my own computer (Windows 10) it seems not to run. The error message after clicking the launch icon is: "no main class" and after closing this dialog another dialog error:"Failed to launch JVM"

Does someone know where is the problem?
Thanks in advance!
