I am attempting to distribute my game with the unity distribution portal. I have filled out all the information on my game, but there is one more thing I have to do before release. The app signature. This has been stopping me from release for a while, I have looked everywhere but now good tutorial is available. I also posted two questions on unity answers and received no reply. My main problem with the app signature is the keystore thing. I believe that is is referring to a java keystore which I attempted to generate but failed. I kept getting and error in the command promt saying that the command "keytool" was an internal or external command. How can I fix this? Sorry if this is confusing, please feel free to ask for specifications. I really would appreciate some help with this, I'm so close to publishing my game. Thanks in advance!
