Where does Lumberyard put its temporary files for install?

I’m seriously frustrated, I tried to install Lumberyard on one of my other hard disks, because my C drive doesn’t have a lot of space left. But the installation failed and It dumped enough crap onto my C Drive to completely fill it up, literally. I cant find where these files are anywhere!

I also tried to look at the log to see where it was throwing them, but it seemed to only show various memory space locations, and a couple hints at the local/temp drive, which i completely emptied and it didn’t help.
