Enter an integer for this feature's install level. Unless the end user deselects features in the Custom Setup dialog, all features with an install level less than or equal to the value of the package's INSTALLLEVEL property are installed. You can change the INSTALLLEVEL property for the entire project in the Property Manager.

The install level feature attribute is compared against the INSTALLLEVEL property at runtime to determine which features are available for installation. You can use this attribute to create specific feature configurations at runtime.

For InstallScript MSI setup projects, this property is used only if there are no setup types defined for the project.
