Hello @pcetp.1​ and welcome to the Community 🙂 ,

Please make sure that the STM32F401RE package is well installed into KEIL MDK.

Could you please share what errors did you found?

Thank you.

New releases of the MDK don't come with the 5.xx compilers, you either have to install them as some sort of legacy pack, or simply bring up the Project Options, and in the Target Tab change the "ARM Compiler" setting to "Use default compiler version 6"

It can be more fussy with the syntax checking / warnings, and might need the command line options cleaned up,but by and large should compile HAL code, and do so much faster.
