Cannot reinstall iPhoto from App Store in Lion My company recently upgraded my laptop to OS X Lion and was pre-installed with iPhoto purchased under a different Apple ID. I have my own purchased version so wanted to update the app, but it asked for the other user's password.

So I decided to uninstall the app using Launchpad and try downloading it again. However, when I go to it in the Mac App Store, the button now says "ACCEPT" and when I click on it, I get this message:


  These apps cannot be accepted on this computer.
  Future updates of these apps can be found through Software Update.


What can I do to get iPhoto to download again?
I ran into the same problem and finally found the following solution on the apple support forums that worked for me:


Launch App Store
Click the "Purchases" tab (the price-tag icon at the top of the App Store window)
Find iMovie in the list
Click its "INSTALL" button
