I need to run a program called Niagara. It will not run with Java 7 so I have uninstalled 7 and re-installed 6. Now, mozilla wants me to install a plugin in order to run the program. When I click install plugin, it takes me to the java site and wants me to download 7.

Do you get any Java error or security messages?

There has been a change in the Java security settings, see:

If you visit a website regularly then a possible workaround is to add the URL to the Java Exceptions Site List, see:

I don't get any security prompts. I just get a msg that says A plugin is needed - please click here to install. After clicking install, it says JRE is not available. I downloaded Java 7.21 (which is what the Niagara people told me would work). It's in my programs list. Not sure why Mozilla cant see it? Because I have 7.21, there is no exception list available. I guess that came out with 7.51.
