How to install flask-bcrypt on Windows?

Question

Flask

I can't install flask-bcrypt at all. There is Windows 7 and Python 2.7.
Upon installation, I get the following:

Tried looking for solutions. I came across the advice to install py-bcrypt, that after that everything should go like clockwork. Through pip and easy_install, this failed for me for about the same reason as flask-bcrypt. Manually installed via whl file py-bcrypt-04.
The installation problem remains.

What I need, in general, is it possible to do somehow? :)

Upd. Could this be because I happen to have many versions of VS installed, from 2005 to 2015? I don’t know where they came from, and why there are a lot of them, I’m not strong in this.
