Hi,
To install the demo data manually you need to:
1. Download it here:
www.hikashop.com/sampledata/dataexample.zip
2. Extract the archive.
3. Copy the folders and files in the upload/safe folder of the archive in the media/com_hikashop/upload/safe folder of your website.
4. Copy the folders and files in the upload folder of the archive in the images/com_hikashop/upload folder of your website.
5. Edit the script.sql file of the archive via notepad and change the #__ prefix of the tables to the actual prefix that you have configured in your Joomla configuration.
6. Import the modified script.sql file in your database via your PHPMyAdmin.
7. Click on the "rebuild" button of the Products>Categories menu of the HikaShop backend.
These are the exact steps that are run by the wizard when it installs the demo data automatically.
