I have tried to install Design Premium CS3 onto my mac. However, it won't install any of the programmes on Design Premium as it says I have Adobe Indesign cs4 already on my mac. When I have tried to get rid of Indesign it is not in my applications folder and I need to get rid of it so that I can install Design Premium. Is there a way I can find indesign and erase it and install Design Premium CS3?
