CodeWarrior in ARM Developer Suite requires a separate license file in addition to the ADS license file. This license file is installed by default into the ADS installation directory and is called license.dat. Because the ADS license file is also called license.dat, the CodeWarrior license file is sometimes moved or deleted by the user in error (for example when installing the ADS license file).

This will result in an error of the form: "The CodeWarrior IDE is licensed and a valid license was not found. Please contact the Metrowerks licensing department.... etc."

Solution
The problem can easily be corrected by locating the file license.dat in the root directory of the ADS CD, and copying this into the ADS installation directory.
