To anyone that can help!
I have had the Adobe CS3 suit for Students and Teachers on my iMac for the past 10 years. I have recently bought a new Mac laptop and wish to install the Photoshop software. I still have the content disks so have been able to install the software. However I no longer have the original box with the serial number. I have gone to the help section of Photoshop and clicked on 'system info'. Here there is a section that says 'Serial Number' with a 21 digit code. However, when typing this code to activate the software on my laptop, it appears to be 4 digits short.
Many thanks advance.
