(Yes, I'm quoting myself.)
To add to this, if you're able to edit the build.prop you can disable camera noise that way, too.
And considering you said you didn't try to install it anyway, I would try that now. There are also plenty of other camera apps that allow you to disable the sound - I wouldn't be so hard-pressed on using the stock app, but to each their own.
