Hi Shahasan,
officially Freescale doesn't have license download for CW4.1.
I suggest you create a service request to Freescale support license team to see if you can get an CW4.1 evaluation license.
which chip do you work with? Freescale has CW for HCS12 v5.1 that covers HC(s)12(X) family.
Have a great day,
Zhang Jun
