Sorry for the late response, this is weird. Could you post the the startup line (ex: "Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 18:41:36) [MSC v.1900 64 bit (AMD64)] on win32") for 32 and 64 bit python.

You may have a too old / new version of Microsoft C++ installed.

Python 32: C:\Users<user>\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pynrfjprog\win_32bit_dll\nrfjprog.dll

Python 64: C:\Users<user>\AppData\Local\Programs\Python\Python36\lib\site-packages\pynrfjprog\win_64bit_dll\nrfjprog.dll

Variable is in line 394 (API.py)

Could you try to print the "nrfjprog_dll_path" variable on line 411 in API.py? I'll need to see which DLL the API is trying to load. Looks like it's confused about the system "bitness".

Strange. Can you check if you have a 32bit version of windows? This page has a guide on how to check it.

Ok, good. How did you install it? pip or github?

Both (32 and 64 Python's) win_64bit_dll folders consists of: highlevelnrfjprog.dll jlinkarm_nrf51_nrfjprog.dll jlinkarm_nrf52_nrfjprog.dll jlinkarm_unknown_nrfjprog.dll nrfjprog.dll

Hi! Did you install pynrfjprog through pip, or by downloading from github?

Could you check the folder "Python 64bit install folder"\Lib\site-packages\pynrfjprog\win_64bit_dll and see if the required dlls are there? If you dwonloaded pynrfjprog manually, just check wherever you installed pynrfjprog, it should have the same folder structure.

It should contain the following files:

nrfjprog.dll
highlevelnrfjprog.dll
jlinkarm_nrf51_nrfjprog.dll
jlinkarm_nrf52_nrfjprog.dll
jlinkarm_unknown_nrfjprog.dll
