you need a newer version of pages to open this document

Folks, there's another situation in which that message might appear.

I have both Pages 5 and Pages 4.3 installed. I'm no fan of the new version, even taking into consideration the recent updates that restored some of the lost features. I do *all* of my own work in 4.3.

However - a friend has asked me to review some documents prepared in Pages 5. I attempted to open the file with a double-click, since doing so will default to the new Pages 5 (which drives those of us prefering to use 4.3 as default rather off the deep end).

The error that started this thread appears if Pages 4.3 is running when you double-click a Pages 5 file. In this instance, OS X doesn't try to open the new Pags 5 app as it usually does. Since Pages is running, it attempts to open the file with Pages 4.3, thus causing the error.

The fact that you can't force Pages 4.3 as the default (using "Get Info", "Open With...", and "Change All") is infuriating. Doubly so when that behaviour is negated when 4.3 is running and you *want* to open a document in Pages 5.

right click open > choose the version you want

I run Pages 4.3 and Pages 5.2 side by side without problem, just don't double click.

That is the trick I use to get my Pages 08 documents open in Pages 08 instead of 09 when I double click!!!!

I'm having the same issue. I did create it in version 5 of pages but still have Pages '09 installed. I uninstalled the latter but I'm having the issue still. This started just a couple of days and only is happening with a few files which is really strange. Some Pages documents created before this are working fine and so are some created after this happened so it simply does not make sense.

Resolution!!! In the end the culprit was my backup syncing software - SugarSync. What happened is when it made a backup and pushed that out to my computers it found a duplicate. In doing so it appends "(computer 2)" to the file name. In this case it actually did that to the contents of the Pages file. If you open the Pages file in Windows, for example, it treats it as a ZIP file. Inside of it several items (e.g. plist files, etc) had "(computer 2)" appended to the file name. After I removed that the file opened perfectly in Pages 5 on my computer.
