Installer error message, please help

[Colo122]

I'm attempting to install lightroom 4 on an imac running with Mac OS X version 10.5.8 and I am receiving this message:

Operation could not be completed. (com.apple.installer.pagecontroller error -1.)

Any suggestions/help would be greatly appreciated. I am only moderately computer savvy and might need any directions dumbed down for me... Thanks!!!

PS- tried restarting the computer with the start up disk and repairing the disk utility. Still didn't work =/

Is this Casper Suite related? Its unclear from your post, but since this is a JAMFNation / Casper Suite forum, I assume so. Going along with that assumption, can you provide some details of when you see this error? In the policy logs? Pushing it via Casper Remote? Something else?

Have you tried installing this manually on this iMac to see if it works or if you get a similar error?

Basically, we need some more details before we can offer help.

According to the Tech Specs Lightroom 4 requires at least Mac OS 10.6.8.
