This was driving me crazy for the last 2 weeks but I finally figured out a fix that worked on my system. Open the launcher, go to "Edit Profile" and then unclick the box next to "Executable". This setting was pointing to the location of a previous version of the java runtime that has been removed, and if you unclick it then Minecraft will find the correct java and work fine.
