I FIGURED IT OUT! IF ANYONES WONDERING HOW TO DO IT HERe IT IS:

First, make sure ProTools is closed, press start, got to my computer, select you hardisk were auto tune is and click program files. (it will tell you that these files are hidden just click view anyway.)

Second, Find your Antares Audio Technologies folder click it and click the folder Autotune RTAS, copy all the files that have the yellow and green gears. Press back and find the Digi Design folder in your program files, click ProTools.

Third, Scroll down to the file that says plugins click, and simply paste the files that were copy'd into that folder!

(Go to Pro Tools, find your effects and there should be an effect that says pitch correction and theres AutoTune!)

I figured that shit out all by my damn self….damn a nigga smart lmao
