B4J Question Standalone package not running

[Toley]

I have a small project that I use to control a 3 phases motor. I would like to make it executable but when I run the Build Standalone Package the exe is created but it does not start when I try to open it. I'm using Windows 11 and it's an office desktop with an antivirus (maybe it's why I cannot run untrusted application). I have also made a test with Zed's MarkCraft application and it do not start either. Is it a known issue ? Any workaround ?

You need to distribute the executable together with the 4 folders.
The run_debug.bat batch file is useful to test the program and see the logs.

It is useful to doubleclick on the run_debug.bat file to see if there is any errors.

Thank you @aeric it looks like there is an external library that cannot be loaded. I don't know if it can be fixed.

Thank you very much @Chris2 It works well with the #5 fix. I was just lucky enough to try with 2 different projects that falls on those "special cases"
