'ARM.CMSIS.4.2.0' is not installed

I would like to load the blinky example on the nRF52 preview development kit. When I try to build the project I will get this error:

Error #541: 'ARM::CMSIS:CORE:3.40.0' component is missing, pack 'ARM.CMSIS.4.2.0' is not installed

But I've already installed the 'ARM.CMSIS.4.2.0' from this link:

http://www.keil.com/dd2/pack/

When I start the Run-Timer Environment manger I will also get the same error.

Why does this error appear?

Do I have to update the keil version to 5.15 when I want to use the nRF52 DK?
