PSQL v11 error 7313: “Product key is already activated on a different machine”

For me this happened when one of my customers computers died with HD-failure. Since it was an old machine we decided to replace it with a new one. When I then tried to use the license key from the old computer on the new one I got this error.

The solution: 

Send an email to:

with the following information:

  • What happened – why you need to deactivate the key
  • Who you are – name and company
  • The license key

I got an answer after just two hours where they said that they had deactivated the key. I then tried to use the key again and it worked!
