IWork apps cannot be opened in Lion.

Question

Moving to a new MacBook Pro with 10.7.3 and iWork 09 apps "cannot be opened because of a problem".Trying to update iWork and keep getting message: "Alert - A newer version of Keynote is already installed" even after reinstalling iWork from the disk.

Answer 1

Find the newer version using spotlight.
Just type "iWork" or "Keynote". Choose the first option in spotlight, "show all".
From the resulting Finder window, sort by 'Date created'. (If that option is not shown, click on any item in the Finder window once, hold down the 'control' key and click again. In the dialogue box that appears, check the box next to 'Date created'. Close the box. In the finder window, sort by Date created.)
From this, you should be able to locate the newest version. Test by double-clickng and see if it runs.
At the bottom of the Finder window, you should be able to see the path telling you its lcoation. If you can't see that, go up to the menubar at the top of your screen and choose 'View > Show Path bar'.
Look at the path bar. If the newest version is not in the Applications folder, quit the app and then move it there. If it is in the Apps folder already, then click on the older versions and see where they are located.
Move all older version to trash, but don't empty it yet.
Instead, restart your mac. Without opening the app first, locate any pages/keynote/numbers file and double click on it. If iWorks opens up as expected, you can empty the trash of the old versions.
