Recovering Activation Key?

I have been running Davinci Resolve Studio on a Linux desktop and it has been great except if I need to do some sound tweaking. So I recently purchased a Mac do so some lighter editing on and I wanted to install Davinci Resolve Studio on the Mac as well, so I could load the project up and make use of some audio plugins I have on the mac that are not available for linux.

However, I cannot find my activation key anywhere. Perhaps the email got deleted? I don't know. I have the serial number and reciept but not the activation code. Is there anyway to recover that code from my linux install or how do I go about getting the activation key back?

Assuming I can have two activated copies on two machines that are not used at the same time?

While that key should be treated like cash, you should contact support. With that serial from the receipt you have a chance.

I'm in Australia and the Australian support people were very helpful and sent me my activation code again. I made sure to write it in a text file in dropbox this time so it didn't get lost.
