My iMac has just been repaired.
It has had a clean install so I have to install my back up to this computer again.
How do I do this?
If I just try to set back CS6 in Programs I get an error 16 code.
What is the best way to do this?
Since I once bought CS4 and upgraded it to CS6 through the years I don't know my exact code.
You must do a new install, not a restore from a backup

-you will need to enter your original serial number during install for non-Cloud programs
To install an upgrade version you must have BOTH your new and old serial numbers
