I downloaded the the latest install package from http://www.astro.louisville.edu and when I try to run update I get the error "Plugin or class not found"  also when I try to install any plugin I get "warning: [deprecation] write(java.lang.String) in ij.IJ has been deprecated"  

I have Java 8 update 91 installed on my Mac and I think it is the latest update

Do you have any suggestions?

Thanks
