When you’re trying to open any of the Adobe CS5 or CS6 applications in Yosemite, you’ve likely encountered a friendly message such as this:

Download the installer and double-click the .dmg file, then follow the installation instructions.
As soon as the installer has finished you’ll be able to open your favourite Adobe CS5 and CS6 apps again. No restart required.
