[solved]update to 2.2.3 gives sql error

-- url of the page with the problem -- : mywebsite.com/administrator/index.php?op...staller&view=install
-- HikaShop version -- : 1.5.5
-- Joomla version -- : 1.7.0
-- PHP version -- : 5.3.26
-- Browser(s) name and version -- : firefox 25.0.1
-- Error-message(debug-mod must be tuned on) -- : Error_message

In process of updating Joomla to 2.5 tried Updating Hikashop from 1.5.5 to latest 2.2.3 with joomla errors turned on get this error: Install is being done from install from directory on the site.

update: the line it balks at is
administrator/components/com_hikashop/install.hikashop.php:491

looking in the code I see this

486 $this->db->setQuery("ALTER TABLE `#__hikashop_cart` ADD `cart_type` varchar(2 5) NOT NULL DEFAULT 'cart', ".
487 "ADD `cart_name` varchar(50) NOT NULL, ".
488 "ADD `cart_share` varchar(255) NOT NULL DEFAULT 'nobody', ".
489 "ADD `cart_current` INT NOT NULL DEFAULT '0'");
490 $this->db->query();
491 $this->db->query();

It seems odd for that line to be there twice...that would probably cause the issue I'm having.

I commented out line 491 and tried over but that gave a new error: this time at line 615
I then commented out lines 614 and 615 and tried over and voila! it installed.

Hi,

Thanks for your feedback.
We will improve the tests during the updates in order to avoid these SQL problems.
