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.
Where the Java binary is not on the PATH, you can update the CML.ini file to point to the full path of the Java binary (javaw.exe) file, as follows:
Applying Licenses
The order in which you apply your Cisco Modeling Labs license is important.
-
You must apply your base license (R-PID) first and then apply any remaining expansion license(s) (L-PID).
-
Applying an expansion license before a base license will result in an error.
To resolve this issue, remove all licenses and then re-apply them starting with your base license (R-PID).

To fetch new node subtypes from the Cisco Modeling Labs server, perform the following tasks:
The updated list of node subtypes is available for use in the Palette view.
