Information in this knowledgebase article applies to:
I'm using the free-to-use license for STM32F0, STM32G0 and STM32L0 devices and since 1st of January 2020, the compiler generates the following error message when I build my project:
Error: C9555E: Failed to check out a license.LICENSE ERROR (R207(2): REGISTRY READ ERROR) Check that your license details are correct in the License Management dialog of MDK. Additional information is available at: http://www.keil.com/support/man/docs/license/license_management.htm If you need further help, provide this complete error report to your supplier or firstname.lastname@example.org. - ARMLMD_LICENSE_FILE: unset - LM_LICENSE_FILE: unset - ARM_TOOL_VARIANT: unset - ARM_PRODUCT_PATH: unset - Product location: C:\Keil_v5\ARM\sw\mappings - Toolchain location: C:\Keil_v5\ARM\ARMCC\Bin - Selected tool variant: mdk_cm0_256k - Checkout feature: LIC0=3A...-.....-..... - Feature version: 5.0201709 - Keil error code: 1 Product: MDK-ARM Cortex-M0/M0+ 256k 5.29 Component: ARM Compiler 5.06 update 6 (build 750) Tool: ArmCC [4d3637]
What do I need to do to make my license work again?
Due to a logistic error, this license ceased to work too early. We have already created and published a new serial number on this webpage. Follow the steps on this page explained under Activation. It is not necessary to reinstall MDK, only the license needs to be activated again.
