I'm attempting to download and install nRF51 SDK from here:
developer.nordicsemi.com/
Note: The links are ABOVE the masthead of the page (very poor layout!)
I click 'nRF5_SDK/'
I Click latest version's folder (currently: nRF5_SDK_v11.x.x/) I Click 'packs' folder
I then download to a temporary folder
I click 'install.bat' in that folder
Answer 'N' (some cryptic question regarding the registry (?) )
This installs the SDK ---- SOMEWHERE!
I've performed a search-by-date to find out where this is installed - unable to locate!
