Hi 
 Unless I have misunderstood things the answer to your question is answered, as @harsha says, in Etan's thread. I'll try to elaborate: 
 As Petter Myhre says in Etan's thread: 
 
 The nRF52 SDK only comes as a zip, it
doesn't have pack support yet. So you
don't install the actual SDK. You just
unzip, and then open a project by
navigating the folder structure. To
open for example ble_app_hrs you open
the project file in examples\ble_peripheral\ble_app_hrs\pca10036\s132\arm5_no_packs 
 If you installed MDK Version 5
Microcontroller Development Kit you
also need to install Device Family
Pack 8.0.3. You can find it here. You
install it by selecting Pack Installer
in Keil and then File->Import 
 
 This means that you download the nRF52_SDK_0.9.1_3639cc9.zip -file and then simply unpack it to a folder of your own choise on your hard drive. There is no .exe or .msi installers file that needs to be executed. The SDK is simply bunch of folders with .c and .h files. 
 Before you can run an example though, Keil needs to know a few details about the nRF52 and that is why you will need to install the Device Family Pack, NordicSemiconductor.nRF_DeviceFamilyPack.8.0.3.pack , that Petter is talking about. Follow Petter's instructions and you should be up and running.
