QGIS 2.16.2 Windows 10 installation error: ImportError: DLL load failed: %1 is not a valid Win32 application

Question

I have just installed QGIS 2.16.2 from binaries. But it can't load QGIS utilis because of this problem:

Couldn't load QGIS utils.
Python support will be disabled.

Any idea how to fix it? I have already unistalled it and install it twice.
