Installing Photoshop CS3 on Macbook Pro, Lion 10.7.5

In attempting to install Photoshop CS3 from the standard installation DVD on my new (mid-2012) Macbook Pro (with OS X Lion, 10.7.5), I ran into an immediate error message as the DVD's setup app started executing. The error had nothing to do with the (often seen) "... install a Java runtime... ". Instead, the message I received was "photoshop cs3 Setup has encountered an error and cannot continue. Contact Adobe Customer Support for assistance."

My solution was to make an image (.dmg) file of the installation DVD on the desktop using Disk Utility (with the DVD mounted, select it on the left side of the Disk Utility window then click on "New Image" and choose the Desktop as the destination). After that, I opened the image file and executed Setup.app (in the Adobe Photoshop CS3 folder). And it installed! I expect this same issue might show up on Mountain Lion as well and, although I haven't tested it, the same solution should certainly be attempted.

This entry might hopefully be seen by someone with the same problem as I was having and, hopefully, the solution posted here will work for you. Good luck!
