Before You Install SQL Server Express Toolkit

Before you install SQL Server Express Toolkit, make sure that you install the correct version of .NET Framework.

SQL Server Express version .NET Framework version

SQL Server Express Toolkit

Perform the following steps in order:

  1. Uninstall .NET Framework 1.2 and later versions from your computer (versions 1.0 and 1.1 do not have to be uninstalled). Then, install .NET Framework 2.0 from the .NET Framework 2.0 Download Center.

  2. Install SQL Server 2005 Express Edition Toolkit from the Microsoft Web site.


Modifying SQL Server Express Installed Components

The SQLEXPR_TOOLKIT.EXE file is run to install SQL Server Express Toolkit. If SQLEXPR_TOOLKIT.EXE is run directly without saving to a folder, the temporary directory where the binary files are extracted is deleted after the installation is complete. If you try to modify the SQL Server Express components by using Add or Remove Programs in Control Panel, the Change button looks for a setup directory but cannot find it.

To modify the installed SQL Server Express components, you must download sqlexpr.exe again from the Web site, and save the .exe to a folder. At the command prompt, change the path to the folder where the .exe is stored, and run Setup by using the SQLEXPR_TOOLKIT.EXE –x parameter. You are prompted to select an extraction/installation directory.

When you have extracted the Setup files, you can use the Change button to make modifications to your SQL Server Express installation by specifying the extraction directory when prompted.
