No Java Functionality After Reinstalling Internet Explorer

ID: Q158163

The information in this article applies to:
  • Microsoft Internet Explorer versions 3.0, 3.01 for Windows 95
IMPORTANT: This article contains information about editing the registry. Before you edit the registry, you should first make a backup copy of the registry files (System.dat and User.dat). Both are hidden files in the Windows folder.

SYMPTOMS

After you reinstall Internet Explorer 3.0, there may be no Java functionality.


CAUSE

Neither the Classes.zip nor Tclasses.zip file is installed. When Internet Explorer is installed, it registers the version of the Classes files in the registry. When Internet Explorer 3.0 is reinstalled, it does not reinstall these files if the version number of the Classes files is greater than or equal to the value in the registry. When version 3.01 is reinstalled, it does not reinstall the files if the version number of the Classes file is greater than the value in the registry.


RESOLUTION

To restore Java functionality, use either of the following methods:

  • Upgrade your version of Internet Explorer to 3.01. To determine the version you are using, click About on the Help menu in Internet Explorer. Builds 4.70.1155 and 4.70.1158 are version 3.0. You can download version 3.01 from http://www.microsoft.com/ie.

    -or-


  • WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 95. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

    NOTE: For information about how to edit the registry, view the Changing Keys And Values online Help topic in Registry Editor (Regedit.exe). Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry.

    Delete the following value in the registry and then reinstall Internet Explorer:
    HKey_Local_Machine\Software\Microsoft\Java VM\ClassesBuild



MORE INFORMATION

The situation described in this article can occur if you install Internet Explorer 3.0 and then remove the Java folders for some reason (such as for troubleshooting purposes).
