During all this time, (A full week of try), i not dare to disturb you, because i say to me, it's surely my fault

But now, i believe i have used all the possibility
Today, because KCC never abandon, i have try the BETA 5 with a new notebook W10 X64 without proxy
The download, working good, and all are done
And after, i have try with a barebone W7 X64 without proxy
Installing with setup JDK and installing with setup B5 and B6
The BETA 5 and BETA 6 have the same behavior
I have this error
Can you adding a LOG or other tool for follow the compilation step by step and see why i have a problem on this W7 machine ?Can't create the app: Syntaxe : java [-options] class [args...].
Or a tool for simply testing JDK ???
Or perhaps you know already why i have this problem
Have a good day
