InstallingSQL Server September 2005 Community Technology Preview ...errors

Hi,

I am trying to install Microsoft SQL Server September 2005 Community Technology Preview.

I get the generic error saying "SQL Server 2005 setup has detected incompatibe components..."

So I checked the C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\SQLSetup0020_Core.log file

which says

C:\SQLENT2005\Servers\setup.exe Version: 2005.90.1314.0

SQL Server 2005 Setup has detected incompatible components from beta versions of Visual Studio, .NET Framework, or SQL Server 2005. Use Add or Remove Programs to remove these components, and then run SQL Server 2005 Setup again. For detailed instructions on uninstalling SQL Server 2005, see the SQL Server 2005 Readme.

I understand that I need to uninstall "Microsoft SQL Server Setup Support Files (English)"

But when I try to do that I get
"A network error occured while attempting to read from C:\Winnt\Installer\SQLSupport.msi"

how do i fix this...how come nobody has a clue....|||Which previous version of Yukon / Whidbey did you have installed. Yukon comes with an uninstaller in the \Servers\Setup Tools folder. Use that to uninstall previous versions.|||When I ran the uninstall program its says

"There are no SQL Server 2005 or .Net Framework components to unistall"|||How did you uninstall the previous version ?|||I didnt have any version of SQL Server 2005.
What I had is the .net Framework 2.0 Beta version which I unistalled as per the reqm of SQL Server 2005.|||moreover the Change/Remove button for SQL Server Setup Support Files is greyed out...so I can uninstall it either..and SQL Server 2005 setup wont run unless I unless
I get rid of it...
what the heck is goin on..
