Huh, didn't know this was an issue. I'm downloading Visual C++ 2005 as I speak. I hope this works...

Well, it gave me the ability to import fbx files, however the fbx import is even smaller scale than the others. Upon importing an fbx it allows you to change the scale of the object before it's actually imported, but I don't think it will do it through normals.

Alright, I scaled the model in Blender by "normals" or so it says, and then exported back to MED as an fbx. When I imported it back into MED, I set the fbx scale to 5.0 and that seems to be a decent size, however it seems like it only scaled globally and not by normals. The shortcuts provided by @Kartoffel don't seem to work. "Alt+S" suddenly makes the model extremely large and the camera cant render the entire thing, and "w" brings up a secondary menu (with the entire object selected) with no option to flip the normals.
I apologize for seemingly being a pain the butt. Something so simple, and I can't figure it out

Well this page says that Alt+S in edit mode is the way to go, too. Try harder!

Maybe you're using an old Blender version in which this feature doesn't exist or uses a different shortcut.

I'm using 2.7 beta and from what I saw there's little to no documentation for it, just 2.6. Don't worry, I'm gonna keep trying
