i have a board nucleo-L452RE-p i installed the package keil.STM32L4xx_DFP.2.3.0 on my keil MDK, i have also installed the STM32CubeL4 package from ST's website.but when i try to start a new project, my processor family is not there in the board selector page. i've added the screen shots for the above problem too, please help me out.
i checked the windows explorer directory you mentioned and the pack was there. the issue was with the installation hence i uninstalled everything related to keil and did a fresh install with a fresh licence and it worked. my MCU is visible now. thanks for the help.
