Hello @DZall.2 ,
Welcome to the STM32 Community :smiling_face_with_smiling_eyes:.
Utilities / PC_Software folder is not included in STM32CubeL0 (V1.12.0) MCU package, nor in STM32CubeL0 (V1.11.0) either. Because once the new devices are delivered in an official release, the patches should not be delivered in the zip.
IAR, Keil and SW4STM32 are supposed to have integrated the new devices.
During the development phase, we need the patches, but at the time of the official release, the devices are available in the IDEs, so we do not deliver the patches.
