Error installing Joomla 3.4.0

Hi,

I just tried on my local, on a fresh Joomla 3.4, I installed the starter version of HikaShop 2.3.5 and no issues.

This error indicates that HikaShop has been previously installed on the website but not removed properly. So Joomla thinks that the HikaShop tables are already there and doesn't install them, but then HikaShop needs them during the installation process to import the default settings, etc.
The simplest is to extract the HikaShop package on your computer, edit the file back/tables.sql with notepad and change all the #__ by jos_ and finally import that modified tables.sql in your database via your phpmyadmin.
That will add all the HikaShop tables to the database and you'll then be able to run the install process again without that error.
