Discovery board IoT node stm32L475VGT6, error: #5: cannot open source input file "stm32l496g_discovery.h"


For my stm32L475VGT6 I have done the basic setup with uVision 5.28 and cubeMx 5.4 to turn on a LED. 

I'm getting the following error:

...AppData\Local\Arm\Packs\Keil\STM32L4xx_DFP\2.1.0\MDK\Boards\ST\STM32L496G-DISCO\Common\LED_STM32L496G_Discovery.c(34): error:  #5: cannot open source input file "stm32l496g_discovery.h": No such file or directory

  #include "stm32l496g_discovery.h"       // Keil.STM32L496G-Discovery::Board Support:Drivers:Basic I/O

I'm not sure if the compiler needs something here? What is also suspicious, although I choose device specific dfp for stm32L475VGT6 in uVision, it downloads/uses files like stm32l496g_discovery. 

Any help would be greatly appriciated :-)
