All,
I am attempting to install Creative Suite 5.5 Design Standard on an iMac Intel (27-inch, Late 2012) running OS X 10.10.5. When installing the suit from Self Service, I receive the error below. It's worth noting that this package has been well-tested. Additionally, the CS5.5 package also failed to install when the contents were saved locally and the installer was run from the machine itself. This would rule out an issue with Self Service.
I am guessing that CS 5.5 is not supported on OS X 10.10.5 but wanted to verify with others.
