installation request after upload files to server

I have installed shopping cart on Linux computer under 1and1 hosting. But I'm working on my local copy, of that.
After some changes I upgraded database and overwrote old shopping cart files on Linux server. My shopping cart works perfect!

But when I try to login to admin page, I get request for the installation.

Hello. Thank you for loading Zen Cart™.

You are seeing this page for one or more reasons:

This is your first time using Zen Cart™ and you haven't yet ....
Your /includes/configure.php and/or /admin/includes/configure.php file contains invalid path information and/or invalid database-connection information.
....
<<<

But I don't find any invalid path in my configuration files.
:shocking:

Sounds like what it says. If you have a backup copy of your store from your server just upload the admin/includes/configure.php file from that. It should work. If not make sure the path to your database is correct.
