RTFM: You must Enable Internet Information Services 7.0 with ASP.net (Windows Azure)

I'm trying out the Windows Azure SDK, and after downloading the WindowsAzureSDK-x64.msi file, I was greeted with an error message:

Now, I was puzzled a little bit, because I had IIS 7.0 and .net 3.5 SP1 installed, but it turned out to be a RTFM Mistake. From the Release Notes:

Windows Vista

1. From the Start menu, choose Control Panel | Programs | Programs and Features.
2. Click Turn Windows Features On or Off.
3. Under Microsoft .NET Framework 3.0, select Windows Communication Foundation HTTP Activation.
4. Under Internet Information Services, expand World Wide Web Services.
5. Under Application Development Features, select ASP.NET.
6. Under Common HTTP Features, choose Static Content.
7. Install the selected features.

Of course, I was missing both options. Installing both caused the Azure SDK to install perfectly fine.
