Java Issues
When installing the Cisco Modeling Labs client, ensure that you have the appropriate Java version installed and that the PATH environment variable contains the path for the Java binary.
Where mismatched architecture versions of Java 6 or Java 7 and the Cisco Modeling Labs client are installed, a Java runtime error is returned and the installation fails.

Applying Licenses
The order in which you apply your Cisco Modeling Labs license is important.

To resolve this issue, remove all licenses and then re-apply them starting with your base license (R-PID).
