Ooops. How can I re-install the Mac App Store? I'm running Mac OS X version 10.7.2.

There's this app called app-zapper. It helps to remove the library and cache files from apps when you want to get rid of an app by "zapping" it. I needed to shave some space. I'm using Pixelmator now instead of Photoshop, so I tried to zap my Adobe folder but instead my App Store app got zapped. I didn't realize it till my trash was emptied. The rest writes itself.

I've tried reinstalling 10.7.2, extracting the App Store.app file from 10.7.2 package (it's incomplete) and re-downloading the snow leopard extracted one (don't work on lion).

How can I re-install the app store?
Many options are available to you:


Restore it from your backup
Copy it from another Mac running 10.7.2
Download and apply the current combo updater (often they contain entire programs, but it's not a guaranteed thing)
Reinstall Lion and upgrade to 10.7.2 - if your Lion install is lower than 10.7.2 try not to run programs until they are all patched up to the same version as your existing software.
