Hi,
Thanks for clarification.
The USB Stick includes an installer and some useful documents. You should get a separate sheet or card with a registration number CWA_BASIC_NL_XXXXXXX printed.
This number has no relation to any OS. You have to register this number on your nxp.com to get the lincese.dat file.
I can confirm thatt the CodeWarrior for MCUs v10.7 should work with the license you bought on Windows 7/10 64bit.
