So the above results confirm that the ProKit libraries are PPC and hence not suitable for your machine.
I don't know how this could happen. It seems like a problem with the ProKit updater that you said you ran.
You should contact Apple about this.

I am including a lot of info in this post in hopes that Google will tag this comment to help others solve the problem easier and faster:

PROBLEM:
Intel Mac will not launch Final Cut, Motion, DVD Studio Pro, Compressor
ProApp.Framework is PPC only
with PPC version of ProKit installed, Console crash.log shows:

Library not loaded: /System/Library/PrivateFrameworks/ProKit.framework/Versions/A/ProKit
Referenced from: /Applications/Final Cut Pro.app/Contents/MacOS/Final Cut Pro
Reason: no suitable image found. Did find:
/System/Library/PrivateFrameworks/ProKit.framework/Versions/A/ProKit: mach-o, but wrong architecture

without any ProKit.Framework installed, Console crash.log shows:

Library not loaded: /System/Library/PrivateFrameworks/ProKit.framework/Versions/A/ProKit
Referenced from: /Applications/Final Cut Pro.app/Contents/MacOS/Final Cut Pro

SOLUTION:
The solution to this problem (which the incompetent Apple support jerkoffs will never tell you - most likely because they are totally uninformed and clueless to begin with), is to get the Universal version of ProKit.Framework (v3.1.1) either from your Intel-based Tiger install DVD (via pacifist [Google it]) that came with your Intel-mac, OR download it from the following URL:

BE SURE TO REPAIR PERMISSIONS AFTER REPLACING/INSTALLING THE ProApp.Framework file into /System/Library/PrivateFrameworks

This will solve your problem. I have a huge headache after figuring this out and thanks to the obscure forums that showed how to do it:

Enjoy.

RANT follows...
WTF does Apple not provide this little file on their support site? It doesn't appear to have been updated by any of the recent FCS/Pro App updates... and it's possible that FCS 5.1 installation will delete the ProApp.Framework that came installed on your computer. WTF do the support jerks do everything to get out of any obligation to help out... BASTARDS!!! :)

Thanks... it worked, and I have opened Aperture, and DVD Pro. I assume that the other apps open successfully at work. OS10.4.10 has been a right headache. What would I do without these forums!!!

I'm sorry if this is a stupid question, but what do you mean by:

BE SURE TO REPAIR PERMISSIONS AFTER REPLACING/INSTALLING THE ProApp.Framework file

I am having this issue with Pro Logic Express 8. I have an Intel iMac running Leopard. I am getting the exact same error message about the prokit framework when I try launching Logic and Aperature.

After installing the framework, launch /Applications/Utilities/Disk Utility, select your hard drive and click "Repair Disk Permissions." This should correct the permissions for the newly installed framework so the System and use it.

Thanks! I'll give that a try.

Can someone please post a link for Prokit.Framework v3.1.1? The link provided (above) doesn't work anymore.

I'm hoping someone can re post this as well, i really need it

thanks

I really hope you guys still read this. I have the same problem and have done everything you've said but my dvd studio pro 4 still won't open. More precisely it only opens for a second and then displays an error message for a fraction of a second and I can only make out the bold words "unknown error" before it closes. Please help!
