Connecting Jlink EDU-SWD mode to Nrf52832

Question

wqewqeqwe.PNG I want to program the nrf52 chip using J link Edu -SWD mode. I actually connected the SWDCLK, SDI, and Vtref and GND of Jlink EDU programer to SWDCLK,SDI,3.3V& GND of nrf52 in my Self designed development board. 
 The segger programmer is detected but the nrf52 chip is not detected. it Shows an error " dll not identified". I am using keil and nrfStudio as programming Software. 
 I am still not sure if the dll file is corrupt becuase i have dowloaded latest Version of Jlink Software and nrfgoStudio. 
 Please guide me to find a solution.

The Problem was i had two Debugging Softwares keil and WinideaOpen open in parallal which were accessing the J-LINK EDU. That was the reason the KEIL could not access the on board chip .Connections were right :-
SWDCLK, SDI, and Vtref and GND of Jlink EDU programer to SWDCLK,SDI,3.3V& GND of nrf52 . 
 I had to close one of the Softwares for the other to get full Access. Also i realised that i was able to establish the Connections only when i configured through J link CMD line - Connect->Device->Speed. I have attached a Screen shot of it. Hope it helps someone having similar Situation.
