error 1603 when installing sql server 2005 sept ctp

I tried to install SQL Server 2005 Sept CTP
and it gave error 1603 when installing MS SQL native client.

What should I do?
As a first step, I suggest you tell us more about your setup, which build you are attempting to install and whether you had a previous build of SQL Server 2005 or Visual Studio 2005 on the machine. That would help us understand a little more about your situation.
