Consolidating two accounts into one

I have two accounts for Avast registered under two different e-mails. How can I without uninstalling and re-installing simply de-register from one account and re-register to the other. Thanks for your assistance.

If you are talking about your my.avast.com account, just abandon one, but first delete the device associate with that account.

That should effectively show in that avast installation as not connected to an account, now you should be able to connect that installation to the other account.

At least that is what I think would happen, not having two accounts to test the theory.
