I have an old appliacation that is browser based. It needs to run in Java 6 update 33 at the very newest. It also requires a plug in of 1.5_06. Using internet explorer 11, the java got updated to version 7 or 8- something from this decade. However, I need to run the application. I can't jam the plug in into the browser to get it to work. How can I back rev the plug in?
