Hi,
The first time you installed HikaShop, the tables were not created.
That's why when you try to re-install it, the SQL request does not return anything, the tables are not there.
The tables are created by Joomla during the installation. When you re-install a component Joomla does not re-create the tables, it call the update system because in the logical way, the tables should be there.
You can uninstall completly HikaShop so Joomla will relaunch the database install (using the file "tables.sql").
You can create yourself the missing tables (using the file "tables.sql" in the "back" folder of the package).
