A Few Notes About SQL Server Installation

For best results, one should install SQL Server on a computer that does not have a prerelease version of SQL Server , Visual Studio 2005, or the .NET Framework 2.0 installed on it. If your computer has any of the prerelease versions on it, they must be removed in the correct order before you can successfully manually install the actual version of SQL Server software. For the correct order of these required uninstallations before you can install SQL Server , visit:

We strongly recommend that you instead run the autoinstall tool (found at the same site), rather than attempting a manual install.

Once the uninstall has been correctly done, you may successfully load SQL Server and begin learning SQL.
