Mac OS: Help Viewer Quits With Type 3 Error

Symptom

Help Viewer quits and displays an alert box with these messages:

"The application "" has unexpectedly quit because an error of Type 3 occurred. You should save your work in other open applications and restart the computer."

Figure 1 Help Viewer alert box; earlier version of Internet Config extension installed.

" The Help Viewer application requires Internet Config 2.0 to run."

Solution

Make sure that Internet Config Extension version 2.0.2 or later is installed in the Extensions folder of the System Folder. If necessary, use the Mac OS Installer to perform a custom installation of the Internet control panel. Both the Internet control panel and Internet Config Extension are installed this way.

Proceed as follows:

1. Open the Mac OS Install application.
2. Click Continue.
3. Select the destination disk from the pop-up menu and click Select.
4. Click Continue twice and then Agree.
5. Click Customize.
6. Make sure Mac OS 8.5 (or your version of Mac OS) is the only check box that is selected.
7. Choose Customized Installation from the pop-up menu.
8. Scroll down to the bottom of the list; click the disclosure triangle to the left of Control Panels.
9. Select the Internet check box.
10. Click OK.
11. Click Start.

This also addresses the requirement for Internet Config expressed in the alert shown in Figure 2. For more information about how Internet Config relates to Mac OS 8.5, please see the following article:
