Runtime Error R6034, after installing OpenCV on Windows 7 for Python3

Asked by At

I recently installed OpenCV. I started by installing Anaconda 3, and followed instructions on building OpenCV found here: https://www.learnopencv.com/install-opencv-4-on-windows/ It installed okay and I get access to the libraries in Python (see output below)

Python 3.6.7 |Anaconda custom (64-bit)| (default, Dec 10 2018, 20:35:02) [MSC v.
1915 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.__version__
'4.0.1-dev'
>>>

However, every time I open the anaconda command line interface, a popup comes up saying:

Runtime Error

Program C:\ ... \python.exe

R6034

An application has made an attempt to load the C runtime library incorrectly. Please contact the application's support team for more information.

I have looked for this error and found that it has to do with MicroSoft build tools conflicts. For example a library is built for msvcr90.dll, then when you go to use this library, the OS finds 2 versions in the PATH.

For me, this only happens in the Anaconda Prompt, so I looked deep into the Path on that environment using commands like $where msvc* etc; however, I can not find any conflicts.

So far it is just annoying, but I would like to resolve it.
