Delete wordpress theme activation code from local

Hi I install my Wordpres theme on local but I would like to delete it because I want to instal my theme elsewhere, but I am getting the message that it still is installed somewhere else.
Can i get the activation code deleted from here?

Hi @huubapd

This isn’t something we would control or have access to. Is this a paid theme? If so you might need to contact their developers or their support.

You could try accessing your site files manually to remove the theme however if it’s not allowing within the WordPress dashboard.
