Can't download updates because "This update is not available for this Apple ID" I keep getting this message when I type in my password to do an update.


  This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or cancelled.


The computer was bought by me and has only been used by me.  What do I need to do to fix this?
Try going to the "purchases" section in the App Store. Accept the free apps like iMovie and Garageband there.
