When you set the Required property to Yes, the end user cannot deselect this feature in the Custom Setup dialog, and the feature will be installed.

| For InstallScript MSI projects, this property pertains only to root-level features. To ensure that a subfeature is installed to the target system, use the Required Features property to make the subfeature a required feature of the parent feature. The parent feature's Required property must be set to Yes.

To change this property's value, select Yes or No from the drop-down list, and press Enter.
