OSError: cusolver library not found

[MxQuantFinance]

Good day!
Studied similar issues, verified paths, commands, ctypes etc.
pycuda examples etc work.
But still can't get skcuda working.

Problem

Error message:
C:\Users\user\Anaconda3\lib\site-packages\scikit_cuda-0.5.4-py3.7.egg\skcuda\cublas.py:289: UserWarning: creating CUBLAS context to get version number

Funny but
libcusolver file name: cusolver64_70.dll

So i renamed cusolver64_11.dll to cusolver64_70.dll and

from skcuda import linalg passed without error

Good question: why 64_70?

Very good news: cusolver_demo_svd.py fired.

Everything was done in Visual Studio 2019
