Notes

• This update release updates only the runtime files for the Microsoft .NET Framework 4. For more information about the details of this update, see the "More Information" section.
• This update contains all the runtime changes from the following update:

  2478063 (http://support.microsoft.com/kb/2478063 / ) Update 4.0.1 for Microsoft .NET Framework 4 - Runtime Update

  Therefore, this update is a cumulative update. Any application built for the .NET Framework 4.01 can run on a computer that has the .NET Framework 4 and the Update 4.0.2 runtime installed. We recommend that applications built for the Microsoft .NET Framework 4.0.1 be upgraded to the Update 4.0.2 runtime. However, this upgrade is optional.

• We do not support any application that this update was used to build on any prerelease version of the .NET Framework 4 such as a Beta. Additionally, we recommend that any such application be upgraded to at least the Microsoft .NET Framework 4 RTM

I've got to say the .Net versioning story seems to be getting more and more confusing...
