Hi,
If you have such message, it means that Joomla doesn't found the extracted package.
Did you well upload the extract package ?
You should have a directory, with all hikashop files and a "hikashop.xml" in that directory.
After that, if you give the directory to the installer, it would found files and install HikaShop.
Joomla would require reading access to the directory (and files).
