Yes, there are some tutorials in the tutorial section. See also this post on how to debug error-codes in Keil. This post shows you how use the configuration wizard tool in Keil with the SDK.

Ok great thanks so very much for your help....its always annoying learning the nuances of a new tool, so far I like it however it can be frustrating. Is there any good sites for example projects or code or tutorials regarding nRF in Keil?

Yes, you can remove it. Click on "File extensions, books and environment" : and delete the target.

Yes I understand but I am still confused...I cant remove maybe the flash_s132_nrf52_3.0.0_softdevice from Keil?

The SoftDevice hex should be located SDK_Folder\components\softdevice\S13x\hex\. The SoftDevice is a precompiled and linked binary, you should never have to “build” or “rebuild” the SoftDevice. If you tried building the application in Keil using the target flash_s132_nrf52_3.0.0_softdevice, the hex file in the SDK might have been removed. You then have to download and copy the hex file into the directory specified above. Use the regular "nrf52832_xxaa" as target in Keil, and the SoftDevice hex should not be deleted/removed.

No No I don't mean overwrite I mean if you press clean build from Keil from SDK any version but I am using 12.1 and 12.2 it actually deletes the softdevice HEX file and I am not sure how to rebuild it...is that even possible? I obviously realize I can just copy the HEX file and I know I can program it from nRF goStudio but that it.....

I am trying to figure out how to stop the Keil IDE from erasing both my soft-device and hex file from project folder?? I don't care if the application gets erased obviously however the softdevice being erased is a bit annoying.....Also I cannot remake the softdevice HEX once erased is this true?

Keil should not be able to overwrite the softdevice. This is Keil µvision 5? What SDK project and version are you using? What are the ROM settings(Start, Size) in the Keil project?

Thanks that's a really great article however it only answers about half the question....I need to know why and/or how to stop the Keil IDE from erasing the softdevice HEX file from the directory when I do a clean build...it erases the HEX from the project which is fine but I dont want it to erase the softdevice as its annoying to copy back all the time after hitting that function.
