I have installed uVision V5 using a community licencse (I use this IDE in education) that expires September 30th.
I do not write down the PSN that the system gave me last year to get current licence.
How can I renove the license to get a new year without installing a new Keil version?
The Arm Keil MDK Community Edition is introduced at:
https://www.keil.arm.com/mdk-community/
Note that a new registration of the Community Edition supports only the latest Keil MDK release.
This is why a new MDK installation always is required.
