when I attempt to reinstall Acrobat CS3 the installer asks for a Premier CS4 disc. I did try out Premier CS4 years ago but have long since deleted the 30 day trial. So what does it take to reinstall Acrobat so I can get back to work. Did installing the trial of Photoshop CS6 mess up CS3?
Erm, where to begin? You are trying to install an older version over a newer version after years only after having trialled an even newer version? This cannot work. There are dependencies for shared components everywhere. Attempt to manually uninstall everything (including the CS6 Beta!), run the Creative Suite Cleaner Tool, clean out the remnants and then reinstall in proper order.
