If there is a newer patch or exe, we don't have it. You can email to us if that is the case.
Patches Scrolls, LIVE normally auto-updates but sometimes (Like in this case luckily enough.) there's separate updates available (Though this looks like someone ripped the files LIVE download directly instead of a contained executable installer.)
Works with the Steam version (Which is what I am using.) and is required for the Minerva's Den DLC to work correctly, currently known what else it does, if anything.
