Wait, what? Why would you launch from the disk image directly? I don't know any program that would reasonably allow that.
You'd be surprised at how many do allow it. It was a last ditch attempt, regardless, so that I could reasonably state that I tried everything.
Apart from that I have way too little info - I need the OS, the model of the computer, it's installed GFX card and system language.
To answer your questions:
The model of the computer is a MacBook "Core 2 Duo" 2.1
The OS is MacOSX 10.5.8
The installed video chip is GMA 950
The System Language is most likely Objective C
I hope that answers your questions; please let me know if you have anymore. I also included the full error log (I think. If not, I need to know what it looks like), so hopefully that will be enough to let you know what's going on.
Thanks for looking into it.
