Based on that error, it sounds like ASP.NET 4.5 is not enabled on your server; this is a separate role feature you must install on your computer/server. It could also be a configuration error, as the message suggested, and you've prevented proget's web.config from removing those handlers at the machine level. In this case you'll need to use the built-in web server, or fix the configuration.
