Trying to update keynote, pages and numbers and keep getting "an error has occurred" message. I currently have iWork '09. I have a 13 inch mid 2009 MacBook Pro and I recently updated to Mavericks.
Unless you are trying to install Keynote, Pages and Numbers on a Mac that was bought after mid October 2013, these applications are purchasable upgrades.
Therefore, Log into the Mac App Store and purchase each one separately.
