Hi Neo,

You are correct - Arm Compiler 6 is bundled with Mbed Studio and it can be used without an external license (which is normally required). However, there is still a licensing check running and part of that check is to confirm that the host's system time hasn't been altered. Is your system time correct? If so, do you have any "future files" on your system (where the time/date stamp is ahead of system time)? If so, you'll need to remove these to satisfy the license check.

Regards,

Ralph, Team Mbed

Thank you. My system time is correct and I do not see any 'future file'.

Please email license.support@arm.com and describe your problem. They used to maintain a utility to discover the offending files, but we don't know if it's still available.
