Click on the link to Sun's Java below, then click on the ''Download JRE 5.0 Update 6'' download link that is in the ''JRE 5.0 Update 6 includes the JVM technology'' section. Download the full ''Windows Offline Installation'' file to your desktop,(it's about 15 MB so a dial-up machine will take 30 minutes or so to download), scan it with your antivirus (just to be sure it's clean). Once it's on your desktop, then open the Control Panel/Add-Remove Programs section and UNINSTALL all previous versions of Sun's Java Runtime Environment. When that's done, double click on the new Java installer file on your desktop to install Java 1.5.

AFter that, since you didn't tell us which version of Windows you're using, please download and install the updated Script engine from the appropriate link below:
Windows Script 5.6 for Windows 2000 and XP
At the link above, you'll need to validate your version of XP which isn't a problem as long as its legal.
After everything is installed, then open the Control Panel, double click on the ''Internet Options'' icon, then click on the ''Advanced'' tab. When that loads, scroll down to the ''Java(Sun)'' section and make sure there is a CHECK mark next to: ''Use Java,....''. Click on Apply. Then scroll to the ''Multimedia'' section and place a CHECK mark in the ''Play Sounds In Web Pages'', ''Play videos in Web Pages'', & ''Show pictures'' box and UNCHECK the box next to ''Show download Placeholders:'', then click on Apply, then Ok. Next, under the "Security" tab, make sure the "Internet" properties are set to "Medium"
Hope this helps.
