After selecting the device, I could not able to select the OS version, Next and Finish button's are disabled at that step. The error message is saying as "A SYSTEM IMAGE MUST BE SELECTED TO CONTINUE". I don't know how to resolve this error. If someone know pls help me to resolve this error. I have attached the screenshot of that error. Thanks in advance

I solved it by pressing enter button for the options that do not hold download button with it. Not a single instruction was there for pressing "Enter" button :(
