kworks: Shared Library Error

This solution was originally posted by Charlene Chausis

Problem: The application "AppleWorks" could not be launched because of a shared library error: "-<AppleWorks><MW_MSL.PPC.Shlb><InterfaceLib>"

As stated in many of the threads about this topic:
1. Be sure the AppleWorks program is in it's proper home (in the AppleWorks folder in Applications)
2. Trash the AppleWorks folder in your Home -> Library -> Preferences folder along with the com.apple.plist file. (Don't trash the Button Bar Preferences if you have customized the Button Bar.)
]3. Use the first aid utility to repair permissions on your hard drive (it's recommended that you run this more than once.

THEN... if AppleWorks still will not launch:
1. Open your Applications folder, and then the AppleWorks folder. You should see the AppleWorks icon and several "supporting folders" (AppleWorks Essentials, AppleWorks Extras, Starting Points, etc.)
2. Control + Click on the AppleWorks icon and select "Show Package Contents"
3. Double-click to open the Contents folder. Here's where the problem is.
4.You should see 3 folders and files. The folders should be named MacOS, MacOSClassic and Resources. In all the incidents I've seen, the "MacOS" folder has somehow been renamed with some long obscure cache-like number. Rename this folder MacOS (be sure to type it exactly like this, no space)
5. Close the Contents folder and Package folder and try to launch Appleworks.
6. Smile!

If this does not work for you, (there was one incident that the above fix did not for me), highlight the MacOS folder and duplicate it. Toss the original and rename the copy to Mac OS. For some reason the copy worked.

The only other known solution is to reinstall AppleWorks 6.
