The Readme for the November 2007 release of the Exchange Server 2007 SP1 SDK include an error. The following statement in the Readme is incorrect:

By default, the Setup wizard installs the Exchange Server 2007 SP1 SDK Documentation and Samples on the drive that contains the operating system (usually drive C), in the folder \Program Files\Exchange Server 2007 SP1 SDK\.

The statement should read as follows:

By default, the Setup wizard installs the Exchange Server 2007 SP1 SDK Documentation and Samples on the drive that contains the operating system (usually drive C), in the folder \Program Files\Microsoft\Exchange Server 2007 SP1 SDK\November 2007.

This error is fixed in the online version of the Readme, but is still exists in the Readme that is included in the downloadable version of the SDK.
