Failed to load the application or run the command "Microsoft.AspNet.Server.Kestrel"

I am trying to deploy my ASP.NET 5 WebApi to a remote server (Windows Server 2008 R2) and I am having problems with it working correctly with IIS.

project.json

{ "webroot": "wwwroot", "version": "1.0.0-*", "dependencies": { "App.Data": "1.0.0-*", "App.Model": "1.0.0-*", "App.Repository": "1.0.0-*", "App.ViewModel": "1.0.0-*", "AutoMapper": "4.1.1", "Microsoft.AspNet.Authentication": "1.0.0-rc2-16009", "Microsoft.AspNet.Authentication.JwtBearer": "1.0.0-rc2-16009", "Microsoft.AspNet.Diagnostics": "1.0.0-rc2-16136", "Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc2-15873", "Microsoft.AspNet.Mvc": "6.0.0-rc2-16377", "Microsoft.AspNet.Server.Kestrel": "1.0.0-rc2-16017", "Microsoft.AspNet.Server.WebListener": "1.0.0-rc2-15932", "Microsoft.AspNet.StaticFiles": "1.0.0-rc2-15916", "Microsoft.Framework.Configuration.Json": "1.0.0-rc1-15666", "Microsoft.Framework.Logging": "1.0.0-rc1-15644", "Microsoft.Framework.Logging.Console": "1.0.0-rc1-15644", "Microsoft.IdentityModel.Protocols.OpenIdConnect": "2.0.0-rc1-211120828" }, "commands": { "kestrel": "Microsoft.AspNet.Server.Kestrel", "web": "Microsoft.AspNet.Server.Kestrel" }, "frameworks": { "dnx451": { } }, "exclude": [ "wwwroot", "node_modules" ], "publishExclude": [ "**.user", "**.vspscc" ] }

when I try to access the application from the browser, I get no response. And when I execute web.cmd on the server, I get the following error:

 Error: Unable to load application or execute command 'Microsoft.AspNet.Server.Ke strel'. Available commands: kestrel, web. System.IO.FileNotFoundException: Le fichier spécifié est introuvable.

Verify that all dependencies are installed on the destination server. Run dnu list in cmd to see all the project dependencies.

If some of them are not installed (they will be red), run dnu restore to restore all packages.

You can also verify that your project completed successfully by running dnu build

Hope this helps.
