Note: This is a Preview release. Therefore, do not install this on machines you depend on. Microsoft Codename Max requires the WinFX December CTP in order to function properly. Max will install this for you. However, if you have a previous version of WinFX Runtime Components, Avalon ("Windows Presentation Foundation"), Indigo ("Windows Communication Foundation"), or Microsoft .NET Framework 2.0 installed, please uninstall before installing Max.
