I've installed KDS 3.1.0 and I don't have options to generate new project for it.
You can directly choose the Processors of "MKE04Z8VFK4"
As so far, there is no Boards option for FRDM-KE04Z, select the chip also can development your board.
Hope it helps
Did you installed the new SDK 2.0? See detail from:Using Kinetis Design Studio v3.x with Kinetis SDK v2.0
Yes I did, but the SDK build site doesn't have option for FRDM-KE04Z (MKE04Z8VFK4).
it does not related with KSDK, because KE04z is not supported by KSDK.
Please, go to Processors and choose specific MCU.
I hope this helps.
OK, I got the impression that it should be supported when looking into supported devices list from page below.
