Brand new to this tool. I installed it. I created a new project and saw that there were only ARM devices.
I followed these instructions: https://www2.keil.com/stmicroelectronics-stm32/mdk
Because I wanted to use STM32 processors. I also installed all the packs for STM32L4 and STM32F4.
When I open uvision to create project I just see this:
I removed the MDK-ARM license and reverted to the MDK-lite license and now I can build my STM32 applications.
Try installing it again, but in another path. I have multiple installations and they all coexist great (with care). I just used C:\Keil_MDK_v5 for the last one I installed.
