Hi. I have an Innovage Digital Photo Keychain & Mac OS X 10.4.11. I downloaded Stuffit Expander so that I could download the photo viewer software. I have the 'Digital Photo Keychain Software.stix' icon on my desktop. I double clicked the icon and a 'Digital Photo Keychain' folder popped up on my desktop. Within the folder, there is a 'PC_AP_setup.exe' icon and a 'Photo Viewer Uninstall.pkg'. When I double click the setup icon, a 'Convert File' window pops up with a selection of quite a few programs to choose from. I can't seem to run the setup. Any advice on what to do?
