We have a setup project where we don't (normally) show the feature list to the user, but instead set feature states based on their system configuration. We've seen that when the Select Feature dialog is skipped, the Disk Space Required value on the Ready To Install dialog is not correct. It is a really low number, or often 0. If we go back and take the route where the Features window is displayed, but don't change anything, then the Disk Space requirement is properly calculated on the Ready To Install page.

Is there a way to prompt the installer to recalculate Disk Space Required when the Features page is not displayed?
