Problems Running Install Script

I am using the host server, Site5.com
I have logged into site5 control panel and created a database for WordPress on my web server, as well as a MySQL user who has all privileges for accessing and modifying it.
I have renamed wp-config-sample.php file to wp-config.php.
and changed my database details.
I changed the folder my wordpress files were zipped to, to ‘Blog’
I uploaded the re-named ‘blog’ folder to my public html folder using FileZilla.

here is the problem.
When I try to go the link I am told to go to in the installation instructions pertaining to Running Install Script, It can not find the website.
https://example.com/blog/wp-admin/install.php.

what did I not do, or should do, in order to get this to work?
