Odk briefcase not working

hi all,
i am trying to download the latest release of odk briefcase but it is not open in my laptop i tried to update Java and re downloaded it again it is still not opening , i am using windows 10

So I think the first thing is to check that java is installed and working.
Can you get the version if you open a command prompt and just type in javac -version ?

If not you might need to set some environment variables - like this:

If that is working, you should try running briefcase directly from the command line by running:

java -jar path_to_briefcase.jar

best regards,
