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>
