The problem is NOT with my code. I just installed a new virtual machine,
and installed python3.5 amd64 + pypiwin32 on it. On that machine, the
test service works perfectly!

So it is with my machine. My machine has Python2.7 32bit, Python 3.5
32bit and Python 3.5 64bit installed. Can this be the problem? But how?

What to do next?
