Re: Find or determine an installed tool from my app and run it using NSBundle and/or NSTask

[Jamie Ramone]

You can't use NSBundle for something like this as your tool is not
inside one. Remember: bundles are structured directories owned and
controled by your code, and a preexisting system-wide one is not. You
can, however, use NSTask for this purpose. Once set up you have the
complement of  the setLaunchPath: method, called launchPath to get
said info. But if you set it up the way you showed in the example,
chances are you already have that info. the method is much more
usefull when you created the launch path from separate strings and
lost them since, in my opinion.

As for the error you're getting I can't help as I don't know what's on
line 133 :P
