SQLite not getting copied correctly with Wix installer

I have an SQLite database in my application which is set as content to copy always. I also have a wix installer, and I include the path to my db there too. However, when I try to perform any action, I get missing table errors, because the database hasn't copied over.

Is there anything else I need to do to ensure the db will be available with the application? Everything is working locally, by the way. It's the installed version that fails.

Thanks in advance.
