Hello,
I can't upgrade SQLAlchemy any more on just one of several Windows PCs.
Windows version is Windows 7 Starter Edition, 32 bit, Python version is
3.4.3, installed SQLAlchemy version is 0.9.7.
With
pip install --upgrade sqlalchemy
I get this:
Exception:

I tried to google the exception, but didn't get anything.
Thanks for hints!
