Python not being detected?

[TheCrowing1432]

So I recently bought a new computer, did a fresh install of Steam, Skyrim and the Mod Organizer, when I launched MO it told me that Python was undetected, which baffled me because I thought Python was bundled in with MO and it would automatically install it where needed. 

How do I enable Python? Do I need to download it separate?

The MO wiki explains what you need to do.
