What does this mean?

  • Application Unexpectedly Quit
  • Type 1, 2, 3, 11 or 28 error
  • Bad F-line Instruction

  • Possible Problems:


    The first thing to do is to make sure that you are running the most recent set of software for your Computer.

    To uncorrupt (or rebuild) your desktop file:

    A good tool for doing this is TechTool. A free version of this is available from their site.

    After the About this Macintosh screen disappears during startup (wait for all of the Icon Parade to finish), press the Apple (Command) and Option keys simultaneously.

    A dialog asking you if you want to rebuild your desktop will appear. This results in the loss of file comments in the Get Info of the Finder. (Not a big deal.)

    To uncorrupt (or ZAP) your PRAM:

    A good tool for doing this is TechTool. A free version of this is available from their site.

    Hold down the Apple, Option, P, and R keys simulataneously when your Mac starts up. The screen will blink, and when the Mac is done loading, you will have to reset your control panels to your desired settings (i.e. your Desktop pattern, your Clock and Date, your Views Control Panel, etc.). Also, if you don't want AppleTalk on, zapping the PRAM turns it on. To fix the AppleTalk problem, just enter the Chooser, and turn it off.

    To track down an INIT conflict:

    Use Extensions Manager, it is made by Apple, and allows you to select which INITs (Extensions or Control Panels in System 7.x) are loaded. Sometimes the conflicting INIT can be loaded by itself without any problems. If you isolate the conflicting INIT, try renaming it either the last or the first name in the alphabet of INITs. Entering a space in the name puts it before the other INITs that begin with a number or alphabet character. Control keys are even earlier.

    Finally, Not all programs require extensions loaded, some will work fine with all extensions off. To turn off all extensions, hold down the SHIFT key upon startup.
    To check your Hard Disk for Fragmentation:

    Two utilities are available commercially to check and /or fix fragmented hard drives: Speed Disk (by Symantec), and DiskExpress II. (Disk Express II has a better track record at this time.)

    What next?

    If none of these solutions appear to fix the problem, then you need to contact the author and tell them what System you are running, the RAM installed on your system, whether your machine has an FPU, and what model of Macintosh you are using.

    The some System information can be found by selecting About This Macintosh from the Apple Menu when you are in the Finder. The RAM installed is also in that window. The author can tell you if the software is compatible with your machine.

    Above all, read the documentation that comes with the software. Many times the author specifies what is required to run the software.
