Q: I have been working with an Evaluation license within CCES which I received from Analog Devices. The license has expired and when I try to enter it into CCES again I receive the following message:


Install License only once.JPG


Why do I receive this error?




A: As the error suggests, an Evaluation license can only be entered once per PC regardless of whether you uninstall or use a different version of CCES. Please contact processor.tools.support@analog.com with a copy of your license.dat file for more assistance with this problem.


A copy of your CCES license.dat file can be found here:

[Windows XP]: C:\Documents and Settings\All Users\Application Data\Analog Devices\CrossCore Embedded Studio\license.dat
