If you didn't tag your app as having Ads, or having in-app-purchases but it is tagged later or released that way all the pre-registrations that happened while not having the appropriate will not be able to auto-install. For legal reasons, the user needs to know what it is signing up to at the moment that agrees to install (auto-install = deferred install). I think that makes sense but obviously apps become less attractive when those tags are displayed. I also think the pre-registration program makes sense for games rather than apps.
