    Exception Details: System.ArgumentException: An item with the same key has already been added

    I'm getting the following error when installing the skin. It's clear that the key has already been written into, I'm guessing - the database, or a new page.

    Umbraco won't fully install because of this error. I can access the backend (Content Manager).I can't proceed.

    Which table of the database must I go to, to remove the duplicate data so I can re-run the skin installation and proceed?

    Is there another way to fix this?

    I have trawled the web and so far been unsuccessful - your help is greatly appreciated.

    Please see error below:
