Disable Control Panels, Extensions, and Startup Items

Control Panels, extensions, and items in your Startup Items folder (such as anti-virus software) may prevent Internet Explorer for Macintosh from installing properly. To disable these items, follow these steps:

1. Press and hold down SHIFT while your computer starts.
   
   NOTE: You should receive a message stating that the extensions are disabled or off.
2. In the Finder, click and delete the Internet Explorer for Macintosh files, and then run the Installer again.
   
   To completely remove all the files that were copied to your hard disk during the installation of Internet Explorer, use either one of the following methods:
   • To completely remove Internet Explorer 2.0 or 2.1 from your hard disk:
     1. Delete the following folders, if they exist:
        • Internet Explorer for Macintosh
        • System Folder:Preferences:Explorer
        
        
     2. Delete the following files, if they exist:
        • System Folder:Extensions:Intel Raw Video
        • System Folder:Extensions:Indeo Video
        
        
   • To completely remove Internet Explorer 3.0 from your hard disk, follow these steps:
     1. Delete the following folders, if they exist:
        • Microsoft Internet Applications
        • My Personal Web Site
        • System Folder:Preferences:Explorer
        • System Folder:Java
        • System Folder:MS Internet
        
        
     2. Delete the following files, if they exist:
        • System Folder:Extensions:Intel Raw Video
        • System Folder:Extensions:Indeo Video
        • System Folder:Extensions:Microsoft PWS Extension
        • System Folder:Extensions:MS IE ActiveX Lib (PPC)
        • System Folder:Extensions:MS Internet Library (PPC)
        • System Folder:Extensions:Jgdw.ppc
        • System Folder:Preferences:Internet Preferences
        
        NOTE: The System Folder:Preferences:Internet Preferences file is also used by Internet Config, and may contain preferences that are used by other Internet programs (mail programs, news readers, File Transfer Protocol programs, and so on). Do not delete this file unless you are sure you have written down all of the settings.

Check for Viruses and Hard Disk Integrity

File system damage and viruses can prevent the installation of Internet Explorer for Macintosh. Use Disk First Aid (or a similar disk maintenance tool such as Norton Disk Doctor or MacTools) to verify the integrity of your hard disk. In addition, scan your hard disk with an anti-virus tool to make sure your computer is not infected with a virus.

Turn Off or Unplug External SCSI Devices

An incorrectly terminated small computer system interface (SCSI) chain may cause programs to stop responding (hang), random error messages to appear, or the system to indiscriminately crash and restart. To troubleshoot the possibility that the SCSI chain is incorrectly terminated, turn off or unplug external devices that are connected to the SCSI chain on your Macintosh.

Other reasons SCSI devices may not work or the chain may be unstable include:

• One or more of the devices in the chain is not turned on.
• Two or more of the devices have the same ID number.
• The chain is improperly terminated.
• The total chain (cable length) is too long (over 20 feet).
• A driver is incompatible with the current operating system.
• A device or another part of the chain is damaged in some way.

Because SCSI device drivers are loaded into memory when the Macintosh is turned on, they can generate conflicts similar to extension conflicts. When you are using a non-Apple formatting tool, contact the tool's manufacturer for compatibility information. Removing internal SCSI devices is best performed by an Apple-authorized service provider.

Install by Using a Different Copy of the Installer

When you downloaded Internet Explorer for Macintosh, the BinHex file may have been damaged due to line noise, electronic interference, or problems with the modem. Download the file again and run the Installer again.

Rebuild the Desktop File

A damaged Desktop file is usually indicated by generic icons in the Finder (desktop) and the inability to start programs. You can rebuild the Desktop file by pressing and holding down COMMAND+OPTION while restarting the computer. Note that rebuilding the Desktop file may purge inactive files and links but leave the damaged set of files. Tools are available from online sources that force the Macintosh to re-create a Desktop file series by deleting them entirely.

Reinstall the System Software

Reinstall the system software only if you continue to have problems installing Internet Explorer for Macintosh. When you are prompted whether to update the current system folder or to perform a clean install into a new folder, choose to perform a clean install. If this procedure is not followed, the Setup program simply updates the currently active system folder, which retains the damaged files or settings.

For information about reinstalling the system software, see the Macintosh system documentation or other printed information included with your computer.

Zap the Parameter RAM (PRAM)

Zapping the Parameter random access memory (PRAM) is one technique for solving various system and program problems on a Macintosh. In some cases, the PRAM may need to be zapped several times. Please note that performing this procedure resets only the first 64 bytes of 256 bytes in the PRAM. programs are available from online sources that completely resets the PRAM.
