error no.1813

I'm trying to upgrade my opencart from 2.0 to 3.0, and when I'm installing the 3.0 I received the message below. The demo worked perfectly fine with older version so I'm not sure why.

Error Code(0): Error: Tablespace '`demo`.`oc_cart`' exists.
Error No: 1813
CREATE TABLE `oc_cart` ( `cart_id` int(11) UNSIGNED NOT NULL AUTO_INCREMENT, `api_id` int(11) NOT NULL, `customer_id` int(11) NOT NULL, `session_id` varchar(32) NOT NULL, `product_id` int(11) NOT NULL, `recurring_id` int(11) NOT NULL, `option` text NOT NULL, `quantity` int(5) NOT NULL, `date_added` datetime NOT NULL, PRIMARY KEY (`cart_id`), KEY `cart_id` (`api_id`,`customer_id`,`session_id`,`product_id`,`recurring_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_general_ci in C:\wamp\www\dev\demo\system\library\db\mysqli.php on line 40

Error: Tablespace '`demo_7`.`oc_cart`' exists.

probably means, that some Extension is trying to create a DB-Table,
which already exists. And since that Code is seemengly poorly written,
OC cannot continue to work. But that's just a wild guess ...

I checked at phpmyadmin, and there is no 'oc_cart' table.
