I have just purchased a new Mac and am attempting to download the CS 5.5 Design Standard suite. The software downloads. When I go to install it I keep getting a message: "install" can't be opened. You should eject the disk image.
I have the original product serial number. I don't know if I need to plug it into the digital certificate or what. Please help!

For Mac El Capitan or the newer Sierra operating system read below
Owners of old programs simply have problems with Mac El Capitan/Sierra... none of which is Adobe's fault... Adobe did not change your old program to make it stop working... Apple changed their operating system and THAT is why your old programs won't work, not because of anything Adobe did... Also... every time Apple issues an update, there is the risk that an old program that HAS been working will STOP working... bottom line, old programs require a matching old operating system
CS6 and earlier programs have not been tested and will not be updated for Mac El Capitan/Sierra
-which means that you try to use CS6 and earlier at YOUR risk of having problems
-you may get CS6 and earlier programs to install and run, or you may not (some do, some don't)
