Leopard compatibility?

I have completed my cocoa applescript project which runs perfectly in Snow Leopard. When I try it on Leopard it wont launch. I’ve seen other posts that say it wont work but dont really describe how to fix it.

What are my options here

Do I need to write it again on a leopard system with a different version of xcode or applescript studio?

Im using xcode 3.2.5 on Snow Leopard


the AppleScriptObjC framework is not available in Leopard, and there is no hack or work around to make it work.
The least common denominator is AppleScript Studio (which is deprecated in Snow Leopard but still works), Apple’s Cocoa ScriptingBridge.framework or the third party AppScript ObjC framework
