I am having trouble re-installing my old CS6 onto my new MacOS Mojave 10.14.6 destop computer. I have tried both; using the installer from my back-up as well as the adobe websites downloadable installer file. Neither are working; they both say error, and that the install is failing to initialize due to a possbile missing file. I have no idea what this means or how to remedy it! Please HELP me! Thank you.
