Update Visual Studio 2012 and after it IIS Express gives an error: "Unable to launch the IIS Express Web Server", when I try to run an asp.net project. Before upgrading all worked fine.
/trace:error mode gave such log
Starting IIS Express ...

W3 Server initializing WinSock. CTC = 264312946

Process Model Shutdown called

Looks like that I need to change config file, because of updating IIS Express, but I don't know how.
