PPK: Unable to connect to the ppk, check debugger connection and make sure pynrfjprog is up to date

CurtisHx

I'm trying to use the PPK with an nRF51 dev board, and I'm getting this output whenever I try to start the PPK Software:

Checking installed packages
pyside:		 1.2.4
pyqtgraph:	 0.10.0
numpy:		 1.11.2
pynrfjprog:	 9.0.0
Warning: The software is tested with PyQtGraph 0.9.10, and may not work with your version (0.10.0)
Warning: The software is tested with np 1.9.2, and may not work with your version (1.11.2)
Power Profiler Kit started, initializing...
Unable to connect to the PPK, check debugger connection and make sure pynrfjprog is up to date.

As far as I can tell, I have the PPK connected correctly. The PPK is on the NRF51 dev board, USB is connected to the NRF51 dev board, Power Select on the PPK is set to "DK", but the application won't start.

    Alright. I got it working. Some things were borked, and I was apparently missing a critical component. NumPy apparently requires the VC++ 9.0 Runtime, which I did not have installed. Installing VC++ 9.0 fixed the problems I was having with NumPy. Apparently, I had python 2.7.10 installed, but the installation was screwed up. I deleted the Python27 folder from C:\ and removed all references to Python from the path variable. That let me completely remove 2.7.10 (I was having problems uninstalling it). From there I could install Python 2.7.12, run the python_packages.bat file, and now the PPK is working.
