In which version of pynrfjprog were you seeing this issue?

simtind commented 3 years ago

This looks like a change in behavior for Python 3.8 that I'm surprised we haven't encountered ourselves. Root cause is that CTypes now doesn't consider the full path as a full path any more, leading to the dll load failing with a weird error message. Python issue regarding the documentation that may provide some context as to why this is a problem: https://bugs.python.org/issue42114

Will follow up internally.

  1. This problem was discovered mainly because a new operating system was replaced.

  2. The new operating system version is:

  3. Run this script directly to re-create the problem: python update.py mfw_nrf9160_1.2.0.zip

  4. Installing this pack directly will solve the problem: DirectX Repair V3.9

Ok, that sounds like you were missing the VC redistributable then. I'm glad your problem got solved.
