XCode changing architecture?

So I created an AppleScript Studio app over the course of the last two days.

It was working fine…

Then I got on another computer, made the icon file, and transferred the icon to the same computer I built the app on.

I added the icon to Info.plist, launched the app, and… Nothing.

Additionally, whenever I try to launch it from Finder, it says that it isn’t supported on my architecture, despite the fact that I’ve built, tested, and re-tested the app on this computer.

Do you know why this happens? How can I fix it? How can I prevent it from happening again?

EDIT: Just to be more clear, when I try to run it in XCode, it processes changes as normal, then says the app launched. However, XCode just loses window focus, and nothing actually launches.

Model: PowerBook G4 (PPC)
Operating System: Mac OS X (10.5)

Sounds like you might have damaged the Info.plist file.

Hm. Is there any way to revert it back to the way it was?

Or do I need to start over? :frowning:
