Error in Keil

[don.vukovic]

I have downloaded the Keil compiler and the Nordic key for same.

When running Keil_v5/UV4/PackInstaller.exe I can not get the update:

Cannot download file developer.nordicsemi.com/.../NordicSemiconductor.nRF_DeviceFamilyPack.8.32.1.pack: Cannot download URL (connection interrupted)

The Keil compiler gets the same error in the example project ../ble_app_blinky_c.eww 57 times:

compiling nrf_sdh_soc.c...
..\..\..\..\..\..\modules\nrfx\mdk\nrf52.h(150): error:  #5: cannot open source input file "core_cm4.h": No such file or directory

What can I do to fix this error.

Thanks
