AppleTalk: Cannot Be Opened Error Message

After installing new system software, I am getting the message that "AppleTalk Cannot Be Opened." Why am I getting this message and how do I correct it.
The resource for AppleTalk services are contained within the Shared Library Manager files, located in the Extensions folder of the System Folder. For AppleTalk services to function properly, both the Shared Library Manager and Shared Library Manager PPC files must be present.

To install the Shared Library Manager files for your Power Macintosh computer, double click the Installer and choose the custom install in the pop-up menu. In the custom install menu list, click on the arrow to the left of the following:
Select Apple Shared Library Manager for PowerPC Macintosh by clicking the checkbox to the left, then click Install.

Note: You can also reinstall the latest version of Open Transport to resolve this issue.
