Hi,
It is really strange that the install by "FTP" does not work correctly.
For what I see, you seems to try to install HikaShop on a local machine, right ?
Did you try to use the zip package ?
The "tar.gz" package require more processing resources to extract the files, the zip have a lower compression but is "easier" to extract.
The "FTP" method allow the server to not make the extraction because it will find all extracts files in a specific folder.
Your error about the SQL is weird because it like it tried to launch the HikaShop installation script without launching the database installation before (which is made automatically by Joomla during the first installation).
Please check if HikaShop is not partially installed in the website, it could explain the database problem.
You can also the zip package which is higher than 2MB so can be refused by your web-server if you have a upload limit set to 2MB.
