SQL Server 2000 on Windows 7

 I need to install SQL Server 2000 on a Windows 7 machine.  When I start the install I get a message "SQL Server 2000 is incompatible with this versions.  For more information contact Microsoft."  I searched the forums but did not find anything about this situation.  Does anyone have any information? And before anyone asks I need to install this version because that is what the customer is using and I need to duplicate their databases.
