Classic app won't launch - Script Editor can't read dictionary

Hi everybody,

Fixed the problem myself - too long and grissly to share - so no help needed. Thanks.

Hi there,

I have a G4 iMac and decided to reinstall OSX 10.4.9 to try and solve a persistent network printing problem. Other than that, the iMac had been stable for 4 years.

After backing up (documents only) to a firewire HD, I performed an erase-install then started to load OSX apps. But I noticed that Classic had not been installed - and after several attempts learned I could not install it from the Tiger dvd or the iMac's original cds. Tried several suggestions from Apple Support but none worked. So I copied the entire System Folder from a G5 (single CPU, OSX 10.3.9).

Now, Classic opens fine on the iMac and one of my classic apps works normally (Wingz) but the other (CAT by Chang Labs) won't launch.
These are old apps, but CAT's essential for my work and I'm starting to panic.

When I launch CAT by double clicking the app directly, or one of its documents, I get the same error message;
"Unable to read the dictionary of the application or extension because it is not scriptable" Then Script Editor launches.

I have replaced the System Folder and CAT app a few times (burn CD, copy across network and using portable Firwire drive) but no change.

Also, I repaired permissions (disk utility) and rebuilt the desktop (cassic pane in System Prefs) but no effect - except it may have restored the app's proper icon instead of the generic one. Now I'm all out of ideas.

Hope somebody recognises the problem and thanks in advance for your help. Cheers, Richard
