I figured it out...It's not pretty. Private/var/folders/m1/mjzxlpzj3gn5qmnl7_psk4s00000gn/C/com.apple.appstore/444303913/mzm.stuhjlip.pkg is the lion file that is currently downloading to my system. Original Post: Where Does Lion Keep App Store downloads? I am currently re-downloading the installer, and the file I am downloading for the lion installer is not in my Applications folder. Also, there is not a ~/library/application support/app store/ folder any more. So any ideas where Lion is downloading itself to via the App Store... the only way I can even see that it's downloading is by looking under Launchpad.
