Feature Selection (SQL Server Express)

The Feature Selection page consists of two panes. The left pane shows a tree view of the features that you can install. Expand a feature to view its subfeatures by clicking the + symbol. When you click a feature or subfeature, the Feature Description pane displays a description of the selection and its disk space requirements.

To add or remove a feature, click the feature's icon, and then choose one of the following options from the drop-down list:

Option	Description
Will be installed on local hard drive	Installs the selected feature in the location shown under Installation Path.
Entire feature will be installed on local hard drive	Installs the selected feature and all subfeatures. Expands the parent feature to view its subfeatures
Entire feature will be unavailable	For a new installation of SQL Server, this option skips installation of the selected feature. For an existing installation, this option removes the feature from the installation. After you select this option, a red X appears on the feature tree next to the feature name, and the icon on the parent feature in the tree view appears gray. Note: You cannot clear a feature if one of its subfeatures is selected. To clear a feature, make sure that all of its subfeatures are also cleared.
Browse	Launches the Change Folders page, which lets you change the folder where the selected feature will be installed. This button is available only for features with a user-configurable installation path. For more information on installation paths, see File Locations for Default and Named Instances of SQL Server 2005 in SQL Server 2005 Books Online.
Disk Cost	Displays the available space for installing to different system drives on your computer. After examining the disk space on your computer in the Disk Cost dialog box, click Close to continue installing SQL Server.
