I'm getting an error on each installation attempt, and have even tried using phpmyadmin to look for duplicate entries or other problems, but I see nothing wrong in the database.
When I try to uninstall it tells me it failed. I have to manually remove every file and each database entry. I really don't think I'm missing anything, I looked at every table. I don't see any entry anywhere that this error is talking about.
Also, this happened on the first attempt, on the clean installation with a new database.
