New laptop, reinstalling my Adobe Creative Suite 6, how do I cancel the previous install to free-up access my code?

I previously had ACS 6 on my iMac and laptop, so two installs in total. The iMac is no longer functional (AKA dead). I bought a new MBPro and need to cancel the installation on the iMac and install ACS6 on this new laptop. How do I free up the code as I believe I am restricted to two installs at any one time? I am not certain I have access to the email address I used upon the original install, this was a couple of years ago.

Thanks for the help.
