I would go ahead uninstall it and then manually go to the java site and download it urself. Just go to google and search for JAVA.
When i go to certain pages i recieve a install on demand box that says download java virtual machine. when i try to dl. i get a setup error and it tells me to go to windows update. i have all the updates. how can i dl it or stop it from popping up?
