I had the same problem and the following procedure fixed it:

I have set the Firewall system manually. This means that, at the time of communication by programs Firewall notify me. Incorrectly linked to "devenv.exe" was blocked by the Firewall. Correct mode of communication "devenv.exe" will solve the problem. "devenv.exe" is located in the following path.

"C: \ Program Files (x86) \ Microsoft Visual Studio 12.0 \ Common7 \ IDE \ devenv.exe"

Devenv lets you set various options for the integrated development environment (IDE), and also build, debug, and deploy projects, from the command line.
