Pages for MacBook Pro with OS 10.9.5
I have a copy of iWork 09 DVD which I acquired to install Pages on my MacBook Pro which has OS 10.9.5 (Mavericks). However, it won't install. How do I go about installing Pages on this computer? iWork has installed on my older MacBook with 10.6.8 with no problem. I'm keen to get Pages on my MacBook Pro, so advice very welcome. Thanks.
MacBook Pro (13-inch, Mid 2012), OS X Mountain Lion (10.8.2)
