title: Keytool opens than closes super fast
body: <p>All- When I tried to open keytool (by double-clicking it in my bin file of my JDK), the window pops up but than closes really fast. I looked at this <a href="https://stackoverflow.com/questions/5983946/tried-many-answers-to-get-my-keytool-exe-to-open-but-failed">question</a> and tried to run it from the command line but was met with this

  Did I type in everything OK or is there something else I can try?</p>
