FTP installation problems

I’ve gone through the entire install process and I’ce done it 3 times but everytime I try to run the install.php file it says that it’s not found. I can see the file in my ftp program so I know it’s there. Anyone know what the problem is?

1.I have created a database, a database user and a database password.
2.I have adjusted the wp-config-sample.php to include the above info and renamed it wp-config.php.
3. Then I uploaded that and all other files to your server, and browsed to https://www.yoursite.com/wp-admin/install.php

ve made sure the database name, user name and password are correct. I’ve double-checked to make sure that they are right in the wp-config.php file and I can see everything on the server. I still get a basic ‘page not found’ error page when I try to go to the install.php page. Here is what it looks like.

“The page cannot be found

The only thing I can think of doing is changing the DB name and user name to the user name I use to ftp to my server. I’m going crazy here so any help is greatly appreciated.
