When you try to upgrade your version of Microsoft Internet Explorer by using the Microsoft Internet Explorer 4.0 installation CD-ROM or the installation files downloaded from the Web and you initially installed Internet Explorer when you installed Microsoft Windows NT Server 4.0, Terminal Server Edition, you may receive the following error message:
Internet Explorer Installation is Incomplete
You may receive additional error messages stating that Setup has not installed the following components:
Internet Explorer Direct Animation Internet Explorer Classes for Java
Also, when you restart your computer, you may receive the following error message while Internet Explorer is initializing:
Unable to install java packages from D:\WTSRV\Java\Classes\Win32ie4.cab, the system cannot find the file specified.
