So re-running the nRF SDK installer will load the Keil packs onto your machine. These packs include all the files and examples you will need.
Please note the pack wants to install to c:/Keil
Recent versions of the Keil tools have their default installation directory as c:/Keil_v5
If you install the packs, you will have these nRF51 device database entries in Keil.
