Hello, I am a student of the Cisco Networking Academy, and run Nightly (recently updated to 38.0.a.1) and have a problem with java. Cisco uses Java to allow packet tracer assessments to be opened from the browser into the packet tracer program on my desktop. Here is the Error I get.

Java Runtime Engine (JRE) Error

No Java Runtime Engine (JRE) is configured for your browser. Install the Java Runtime Engine and ensure your browser supports it. Review the setup procedure located in the Networking Academy FAQs under the Help link.

You may have to install Java's latest version if you have not already and activate it in Nightly.

Please make sure that it is enabled and this version is installed:

32-bit version of Java (7 67)
