This is what I get when I click the "Play" button:

Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Users\R\AppData\Roaming\.minecraft\versions\1.8\1.8-natives-49905263766385\lwjgl.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform

What does that mean and what do I do to fix it? D:
