Here's my situation. I have followed the exact instructions on wordpress codex page about moving a site to another server. Here are the step's i have taken.

1. Export a copy of my database
2. Make a new database in the new server
3. Import the database I exported earlier
4. Upload a copy of my Wordpress files via Ftp
5. Use this script to change all my local url's to new one's
6. Make changes to my wp-config.php file according to the new server(I did not forget table prefix. Although it has some uppercase characters in it )

And then when I try to open my site on the new location it just directs me to wp-admin/install.php Now just to make the scenario clearer: The destination folder(on live server) is a sub directori in a public_html folder which already has another wordpress install inside it(I'm saying this just in case it should matter)

My .htaccess looks like this

    # BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /subDirectoryName/
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /subDirectoryName/index.php [L]
</IfModule>

# END WordPress

I have tried checking and repairing my tables via phpMyadmin but everything seems to be ok there and has no effect on the problem.

I also tried emptying the database on the live server and go through with the install. And it installs with no problems and everything works fine but, well I have no use for another clean install. But I think this at least rules out any trouble with wp-config file. I'm using Wordpress Version 3.3.1

So I guess the big question I'm left with is: Why isn't wordpress recognizing my Install after migration?

Any help much appreciated!
