Serial number and activation key for CS6 for MAC

[saraa65073090]

Hi

I worked as a consultant in 2012, the company I was working for bought me a license for Indesign and Photoshop CS6. I added it to my old MAC and now I want to install it on my new macbook air. However I don't have the serial number or activation key anywhere. How do I get a hold of those when they are not on my adobe page?

I have contacted customer service but they could not help as they do not offer technical support for these types of licenses.

PLEASE HELP

Regards

Sara

I run CS6 just fine on El Capitan
