When trying to install Lightroom 4 on my mac os 10.5.8 I'm getting this error message: Operation could not be completed. (com.apple.installer.pagecontroller error -1.)  Suggestions?

You are getting this error message because your computer doesn't meet the minimum system requirement.

Check the link for tech specs :- http://www.adobe.com/products/photoshop-lightroom/tech-specs.html

You need 10.6 or later
