Need to buy Atom again?

I bought Atom in 2015
I now want to instal Atom on my new computer. Do I need to buy atom again? If not how do I recover the activation code that I used before?

If you bought Atom anywhere, you’re a victim of fraud. It has been open-source since mid-2014 (v1.0 came out a year later in 2015) but was freely available from the very start.

Are you sure you’re not confusing it with Sublime Text?

I didn’t purchase Atom. I purchased Houdah Spot. I got confused about which programs that I’m having trouble with loading on my new computer. BTW both are now on there. I got my Houdah Spot problem sorted out.
