New user - running demo_man gives errno 10013 -

[Henrik Andersen]

I've installed the software for the first time, and tried to follow the tutorial.

After downloading demo man, and trying to run it, I get the error:

OSError: [Errno 10013] error while attempting to bind on address ('127.0.0.1', 5051): an attempt was made to access a socket in a way forbidden by its access permissions

MPF run loop ended.

After that the system stops.

I've noticed that the documentation says that demo_man version and mpf version must be the same. However the newest demo_man is 0.52 and I'm running 0.53 of mpf. Is that the reason? If yes - is there a 0.53 version of demo_man on it's way?

By the way - I run the mpf in administrator mode.

More details:

Ok - figured it out.

This problem came up because I had another site running on port 5051.

I went into IIS admin and stopped the other site. Then everything was working fine after that.

Hope this helps someone else.

Thanks!

Welcome to MPF! Thanks for following up. Will add this to the known problems section of the tutorial.
