Heal undead

I know this has probably been asked but I cant find quite the answer im looking for.

I cant, for the life of me, get dawnguard to open in creation kit. Crashes everytime. I only want to open it to see how the heal undead spell is scripted for an idea that i have.

So ignoring my issue with dawnguard, can some one tell me a simple way to get a "heal undead" spell to work in vanilla creation kit?
