• Microsoft does not provide a downloadable version of the Microsoft VM for computers that do not already have the Microsoft VM installed. If you do not have the Microsoft VM installed, you cannot install updates to the Microsoft VM. Windows Update does not offer updates to the Microsoft VM if the Microsoft VM is not installed on your computer.
• Make sure that you are not currently using the Microsoft VM when you try to update it. If you have run a Java applet in a session of Internet Explorer, you must quit Internet Explorer before you install updates to the Microsoft VM. If you are using Internet Explorer 4.x or later with Active Desktop enabled, you may have to restart your computer (after you temporarily remove any Java components from your Active Desktop) to unload the Microsoft VM.

To determine if the Microsoft VM is installed, or to determine the version that you are running, locate the Msjava.dll file in the %Windir%\System folder or the %Windir%\System32 folder. Typically, you can use the Microsoft VM Command Line Interpreter (Jview.exe) to determine the version of the Microsoft VM that you are running. To do this, follow these steps:

1. Click Start, and then click Run.
2. In the Open text box, type the command for your operating system, and then click OK:
   • command.com (Microsoft Windows 98 or Windows Millennium Edition)
     
     -or-
   • cmd (Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003)
3. At the command prompt, type jview, and then press ENTER.
   
   If the Microsoft VM Command Line Interpreter (Jview.exe) is not installed, you receive one of the following error messages:
   • Windows 98 or Windows Millennium Edition
     
     Bad command or file name
   • Windows NT 4.0, Windows 2000, Windows XP, or Windows Server 2003
     'jview' is not recognized as an internal or external command, operable program or batch file.

To determine the version of the Microsoft VM in this case, open the %Windir%\System folder or the %Windir%\System32 folder in Windows Explorer, locate the Msjava.dll file, right-click the file name, and then click Properties. On the Version tab, note the version File version.
