I downloaded shimeji-ee, and I have the latest version of java. I already extracted the files and stuff, but when I tried to open it (in the jar. version), it made me choose which app I wanted to download it with (notepad, paint.net, etc...). So I manually searched for javaw.exe (like you said in the comments) and tried to open it using that, but nothing is happening. What should I do now?
EDIT: I tried to open it with another file, javaws.exe. It says "Unable to Launch the Application".
