I have just bought Lightroom 4 on CD and have ben trying to install on my imac with OSX Snow Leopard 10.6 I believe. I When I try to start the install, I get the following -
The operation couldn't be completed (com.apple.installer.page controller error -1.) couldn't open 'Adobe Photoshop Lightroom 4.pkg'
Can anyone help with this?
I downloaded the software directly as you suggested, but still the same error message comes up when I try to install. I also had to do the same thing with my Canon Utilities software, but it doesn't work properly on the mac either. I am begining to suspect that my imac is too old to work with the latest programmes.
