Possible Cause

Java Runtime Environment Incompatible
Problem
The CTC application does not run properly.
Possible Cause
The compatible Java JRE is not installed.
Solution
The JRE contains the Java virtual machine, runtime class libraries, and Java application launcher that
are necessary to run programs written in the Java programming language. The NCS CTC is a Java application.
A Java application, unlike an applet, cannot rely completely on a web browser for installation and runtime
services. When you run an application written in the Java programming language, you need the correct JRE
installed. The correct JRE for each CTC software release is included on the Cisco NCS software CD. Complete
the
Launch CTC to Correct the Core Version Build, on page 55
. If you are running multiple CTC software
releases on a network, the JRE installed on the computer must be compatible with the different software
releases. The following table shows JRE compatibility with NCS software releases.
