FIXed it. I had the Java JDK also installed , uninstall that and now all is wonderful. Thanks

I have the same problem. Win 10 , and Java16.0 . I get the popup screen coming up instantly then disappearing. Running it from a cmd prompt - the command line stays, the java is still running. From the Resource Monitor I see it still running. Is there any way to get output of the errors or to interrupt it and find out where it is looping? Thanks, Andy
