Installing Creative Suite 5 Design Standard, "Install can't be opened"
I bought a 2015 iMac and am installing CS5 on to it. My CD did not work so I downloaded it instead. When I double click the install icon, I get a warning "install can't be opened, you should eject the disk."
I bought this program and have a serial number so I don't know why I am getting this warning.
Help?
