hey guys!

finally got oblivion collectors edition! really happy about it all!
since its only oblivion on its own, i also decided to order shivering isles expansion pack (physical copy) and kinghts of the nine (physical copy)

shivering isles just came yesterday and i insterted the disk now and its just viewed as a disk with data on my computer... i open it up and it has all of the data and files for shivering isles yet there is no prompt saying "would you like to install shivering isles?"

im really confused right now, can anyone help me?

thanks!
