Hi,
Please re-download the HikaMarket package and please check that you right have in the file "install.hikamarket.php", in the archive file, the version "1.4.3" noted.
I used the same package that was online to update the demo website and the version is good ; so I guess that the downloaded file is not the right one (maybe a cache problem from your browser ; which would be weird due to the patch we made in the patch for that).
