Hi,

I am doing a re-build of a website for a customer. They used to use HikaShop with great success, and want it re-installed on the site.

I have downloaded the latest version of HikaShop starter (as joomla has updated since I did the first build), but when I try to upload the .zip installation package I get the following error:

Error

I am using Joomla 3.6.2.

Any help appreciated.

Thanks
S
