Where I can find SN in an already packaged Photoshop CS6?

Hi guys,

my problem sounds like this: I'm a software packager and I must package Photoshop CS6. I've received from someone an already packaged application - it was packaged using Adobe's tools.

I've asked for the original source files and serial number and he said they don't have them any more - they are using what they gave me and they thought they don't need other files.

The idea is that I need to see what serial number was used to package the application (to see when it is expiring, what kind of license is, etc.).

Does anyone knows where it can be found? Or if there is a file containing the serial number?

Thank you!

Best regards!
