Mac OS: "Could Not Find a Translation Extension" Message

If the preference file for File Exchange or Mac OS Easy Open is unusable or out-of-date, the Finder may be unable to locate the application with which to open (or translate) a file. This article explains how to re-create and rebuild the preference file.

Symptom

When you try to open a file from the desktop, an alert box appears with this message:
However, you know that the necessary application program is installed on the computer.


Solution

Re-create the preference file(s) that store the associations between files and their applications/translators and then rebuild the Desktop file.

Step One: Re-Creating Preferences

Follow these steps to re-create the preference file(s):
Step Two: Rebuild the Desktop file

For complete information on rebuilding the Desktop file, refer to article 10182: "Mac OS: Rebuilding Desktop File and Icon Recovery"

Note: Even after following these steps, double-clicking on certain files will result in the symptom described above. These include files that do not contain type or creator information, or files whose filename extension is ".exe". Files with a filename extension of ".exe" are executables for MS-DOS, and require MS-DOS or Windows emulation software to work with Mac OS-based computers.
