Hi.
My system :Win 10 Pro
Java 8 Update 241
B4J 8.10

When I run B4JPackager11, it never finds the META-INF \ MANIFEST.MF file

Directory and file are missing.


If I trick and set PackageName = "b4j.example" so that it runs, an EXE comes out.

But I can not start this EXE.
What problems do I have?

The system can not find the path specified

Not relevant. B4J only uses the Java that is set under Tools - Configure Paths.

This is a mistake.

And the solution is to follow the installation instructions...

This was the situation at the beginnig. But the problem occurs.
I deleteted now the Java SE DEv Kit 13. Compiled again and the EXE run

Additional Question:
The exe need the subfolders /bin and /lib
Without the subfolders the exe dont run
Is that planned?
