I think "Don't worry about it. Thank you all the same." is correct. For example, you would say it if you have asked someone a question and they don't know the answer. They will say "Sorry, I don't know" and you would then say "Don't worry about it, thanks all the same."

Pero que es lo que quieres decir? Gracias igualmente? En ese caso creo que esto sería correcto: Thank you equally
