ImportError: DLL load failed: The specified procedure could not be found.

Problem Description

There’s some problem with my spyder 4.0.0 installation.

What steps reproduce the problem?

1. I installed Anaconda and updated spyder to 4.0 version
2. When I run spyder from the shortcut, equivalent to running C:\Anaconda3\pythonw.exe C:\Anaconda3\cwp.py C:\Anaconda3 C:\Anaconda3\pythonw.exe C:\Anaconda3\Scripts\spyder-script.py I get the error posted below.
3. However, when I run spyder directly from C:\Anaconda3\Scripts\spyder.exe cmd opens with messages: Attribute Qt::AA_ShareOpenGLContexts must be set before QCoreApplication is created. Attribute Qt::AA_UseSoftwareOpenGL must be set before QCoreApplication is created. and spyder runs without problems

The error is:

I had the same problem when using miniconda. What helped me was updating the pywin32 package (and its dependencies): conda update pywin32

Does anyone have a proper solution for this problem
