This will install the Microsoft Java on your computer.  I recommend that you search your hard drive for the file MSJAVA.DLL and DELETE it first.  That will assure that the java gets installed properly.  You may need to restart you computer before you delete the file.

Click There -> msjavx86.exe

THEN select "Run (or Open) this program from it's current location" from the download dialog box.  
<you may get a Security Warning.  Select YES if you are asked if it is OK to install and run the file>

(Netscape users must select save, the file name is msjavx86.exe  and run it.   If you can not find the file after you download it use the Windows Find Tool located in Start->Find->Files or Folders.

Click Here for the java update that updates your old java to the most current.  You must have java already installed
