I give up! Installing SQL Server 2005 Express

I have given up hope for installing SQL Server 2005 Express on my computer. When I run the installer I get this message:

SQL Server 2005 Beta 3 Setup has detected incompatible beta components from Visual Studio or SQL Server. To proceed, use Windows Add or Remove Programs to remove previous SQL Server Yukon components, SQL Server Support Files, .NET Framework 1.2 and 2.0. Then run SQL Server 2005 Beta 3 Setup again. For detailed instructions on uninstalling SQL Server builds, see the SQL Server 2005 Beta 3 readme file.

After installing and uninstalling the .NET framework a few times, I am guessing the problem has something to do with my SQL Server 2000 developer edition installation. I don’t want to uninstall it because I still need to use the Enterprise Manager.

Is anyone running SQL Server Express with a previous version of SQL Server on the same machine?

What are my SQL Server Support Files anyways?

Update: I did get SQL Server Express 2005 Installed, however here’s how I am currently installing SQL Server on my Mac.
