help JPCSP not working

[hyakki]

the bat file pulls the path from the registry so if the key doesn't exist or the path is wrong that could cause the problem, older versions used to do a direct approach (though both should be ok to use unless its really old then you might need to add the set path line)

In my launcher i just read the java.exe from the windows dir since that usually redirects to the latest java installed so far I haven't had any problem reports with doing it that way so it seems good.
