Steam is saying I have to download the game all over again, but I have already done so. It is on my external hard drive instead of my SSD in my laptop, to save space. I haven't really had this problem before, any ideas what may have happened?

    Is this the first time you've installed a game to this external drive? Did Steam install it there, or did you move it there manually? Has the drive been unplugged since installing the game to it? Apr 1, 2016 at 16:35
  • Have you set that specific HD+directory as a Steam Library inside Steam?

The game needs to be in the correct folder.

It has to be in your <Steam Directory>\Steam\SteamApps\common folder. If it is in one, make sure Steam recognizes it.

I would try clearing some space and installing Skyrim on your SSD.

Steam tends to be picky about which folders it'll pick from.
