When I insert the Lightroom 4 disc into my Mac I get this message: "Operation could not be completed. (com.apple.installer.pagecontroller error -1), Couldn't open "Adobe Photoshop Lightroom 4.pkg"
Does anyone know how I can get past this and get my upgrade installed?
Many thanks for help with this problem.
Which MAC are you on....can you let us know the more ddetails of your OS.
I think it doesn't meet the minimum system requirement
You have to have Mac OS X 10.6.8 (Snow Leopard) to install Lightroom 4.
