So, you've completed migration of your Wordpress, restored all the tables, copied all images and it should now open your website but instead it just sends you to

www.your-domain.com/wp-admin/install.php

Everything seems to be in place, it just doesn't want to work.
Your issue lies within wp-config.php file. You have to double check the $table_prefix field and make sure that it corresponds to table prefixes in your actual database.

/**
* WordPress Database Table prefix.
*
* You can have multiple installations in one database if you give each a unique
* prefix. Only numbers, letters, and underscores please!
*/
$table_prefix  = ‘wp_’;

It has to correspond to the last letter and watch out for UPPER/lower case mismatches. Use phpMyAdmin to examine your tables. Each and every table in your database has to have the same prefix that is set up in your wp-config.

Correct table names in your database:
wp_commentmeta
wp_comments
wp_links

Incorrect table names in your Wordpress database:
WP_commentmeta
wP_comments
wp_wp_links

Even one symbol difference will force your WordPress into installation mode.
