解决方案

Got precisely the same error and came to this question. As @SpaceBison mentioned in comments, this answer describes the solution - http://stackoverflow.com/a/12867753/404099. I spotted it too late and it misses some steps. This is what worked for me:

Windows Server 2012, IIS 8.5. Should work for other versions too.

Go to server manager, click add roles and features
In the roles section choose: Web Server
- Under Security sub-section choose everything (I excluded digest, IP restrictions and URL authorization as we don't use them)
- Under Application Development choose .NET Extensibility 4.5, ASP>NET 4.5, both ISAPI entries
In the features section choose: NET 3.5, .NET 4.5, ASP.NET 4.5
In the web server section choose: Web Server (all), Management Tools (IIS Management Console and Management Service), Windows Authentication - if you are using any of it
