Both @dave3 and I are simply trying to get more information from you so we can help you get to the bottom of the issue. At this point all I can say is - if you have uploaded the files to the correct place and your web server and PHP is configured correctly then everything should work.
If it doesn't work then significantly more information will be required before we can begin to help.
I think it must be english , but the installation process has some steps and we would like to know in which one do you see this error. Directly on start?
