C# 2013. Web MVC app, Win 7/64 pro ISS 7, .Net 4.5

This morning I wanted to see if I could get this MVC app running locally outside the IDE.

Before I started I was able to run it within the IDE.

I published it to a folder a few days ago and today tried to run it locally. NG always get 503 errors. Tried some IIS restarting of app pools, etc., re-boots No luck.

So I went back to trying it in the IDE and not I cannot run it at all. Get
'Unable to start debugging on the web server. Unable to connect to the web server' when I run as Admin. (I do have admin rights) and 'Unable to start debugging on the web server. Could not start ASP.Net debugging.'

I get these messages run running in debug or release mode.

Nothing except debug to release and back was changed in the project.

I did create a new dummy web page and that came up.

Please Help, I am now dead in the water on this.

What I have tried:

Restart application pools
rebooting the system

You're not the first one to come up against this and there's a list of possible causes. I suggest you Google for "iis express unable to start debugging on the web server" and start reading. There's a lot of stuff to check.

Already did but they talk about basically new projects. It was working a few hours ago then it stopped. So I would understand if it was the first time or did some massive updates but that didn't happen. Just tried to enable the published app to run locally. I will keep looking but I looked for an hour already.

I have now tried deleting the IISExpress folder (no help)
I then started without debugging and now get a 503 the Service is unavailable.
All pools are started.
