Can you post the path to javac.exe under Tools - Configure Paths?

Thanks for the reply
C:\Program Files\Java\jdk-14\bin\javac.exe
Is it correct?

Not at all. Follow the installation instructions: https://www.b4x.com/b4a.html

Hi there many thanks . I sorted it out . Used a lower version of java . I think my firewall was blocking it . and I did not realise it.
Many thanks once again . Windows firewall blocks a lot of stuff that one does not realise. Now I can get on with your tutorial!!
C:\Program Files\Java\jdk-11.0.1\bin\javac.exe
