Hello all and thank you for the interest in my problem.
I just bought a new Asus computer (Asus Q501LA) with Windows 8.1 operating system. I downloaded and installed Java and based on the tests on Java website it seems to be working. I tested here: http://www.javatester.org/version.html and here: http://java.com/en/download/uninstallapplet.jsp
It says I have Java version 7 update 55.
Now the problem is that when I try to open Scottrade Streaming Quotes which is a Java based platform, then the Java installation starts again and after the installation nothing happens. I have Java enabled on all browsers and I tried it with Internet Explorer, Firefox and Google Chrome. Latest versions of everything. Each time I try to open Scottrade Streaming Quotes, Java set-up/installation starts and after that is finished, the Streaming Quotes still does not open. No error messages or anything.
Has anyone had a similar problem or knows how to help? I already uninstalled my antivirus and firewall (AVG), because originally it was causing some problems. Then I uninstalled Java and installed again. Did multiple restarts in between the different uninstallations and installations. What should I do now?
