Is there a way to get old serial number from programme already installed?

My apologies if this has already been asked but I couldn't find anything.

I'm having a trouble finding any account information or order information (there is nothing there).  It's been a while since I installed the creative suite so i was looking to register an older product hoping I can put my adobe programmes from my old laptop onto my new computer, but I cannot find the product serial number anywhere (not in an email or anything).

Is there a way I can somehow get the information from my laptops already installed adobe programmes? I'm genuinely stumped.
