What installer version do I have?

[nimonster]

What is my Mountain lion installer version (one one in my applications folder if you don't know what i'm talking about" . I know it is either 10.8.0 or 10.8.1. I do not want to upgrade it or check any dates of the files. How do I tell?

anyone? I don't want to just upgrade it because the new version does not boot on my laptop
