It looks like the later 32 bit wheels include 64 bit versions of the 
MSVC DLLs. I assume that if the correct 32 bit versions are installed 
elsewhere on a system then these will be picked up and the ones in the 
wheel would be ignored. That would explain why nobody else has reported 
the problem and why my release tests didn't register it. I assume that 
you don't already have the 32 bit versions installed elsewhere.

Can you try installing them from the Microsoft package...


...to see if that fixes the problem.
