How to solve a "HTTP Error 404.3 - Not Found" error?

Question

Simple problem. I start up VS2008 and create a new WCF Service application. This will create a default application with a few test methods showing it works. I press CTRL+F5 and it does indeed work! Great! However, it uses the Visual Studio Development server, which I don't want to support. So I go to the project properties, switch to using a local IIS Web server, create the virtual directory and press CTRL+F5 again. And this "HTTP Error 404.3 - Not Found" error is greeting me back. So something in my IIS7/Vista-64 setup is wrong. What could I be missing?

Accepted Answer

Click Start -> Run `cmd` and type:

```
cd "\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation"
ServiceModelReg.exe -i
```
