Minecraft Launcher isn't exactly working for me.

Whenever I try to launch the game, it fails in the final stages and provides me with this error message: 
Unable to locate the Java runtime.
Error details: The operation completed successfully.
Filename on disk: javaw.exe
Path: C:\Program Files (x86)\Minecraft Launcher\runtime\jre-x64\bin\javaw.exe
