Thanks for the fast reply.

Folder jdk-19.0.2 does not exist, its content is directly in C:\Java.

The installation instructions are not very clear, and not automated.
And the compile window too small and its content not styled.
Could you improve these for next version ?

The most updated installation instructions are always here: https://www.b4x.com/b4j.html

You can resize the compilation window and it will preserve the new size.

For B4A, the updated instructions are available here: https://www.b4x.com/b4a.html
