Error loading mkl.dll : not valid win32 application

When I try to multiply matrices, I get the following error:

Error using  * 
BLAS loading error:
mkl.dll: mkl.dll is not a valid Win32 application.

I am using a fresh install of 64-bit MATLAB R2018a on a 64-bit, Windows 10 PC.

The file mkl.dll is stored in ...\MATLAB\R2018a\bin\win64 so I assume it is also 64-bit.

Why does MATLAB want a 32-bit file and how do I fix this problem?
