Composer can not find files during installation

I have installed invoice plane on my local pc on a folder invoicedemo and it was fine. The I uploaded database and file on my Server which is Debian 8.1 Jessie apache 2.4. on a floder I had some problems so I decided to install it from scratch.
I downloaded v1.5.2 on the path /demo/timologia, unpacked the files, I renemaed ipconfig.php and entered at the URL parameter of the file.
Then on my browser I run but I got the error

Warning: require_once(/var/www/clients/client1/web1/web/invoicesdemo/vendor/composer/autoload_real.php): failed to open stream: No such file or directory in /var/www/clients/client1/web1/web/demo/timologia/vendor/autoload.php on line 5

The directory “invoicedemo” does not exists on my server. Why is it trying to read its files there?
Can someone help me please?

thanks Christoforos

I will reply my own question, because after 45 minutes the installatin started normally.
I dont know why, seems something was cached on my server or something similar happened. I will investigate it furher and If I found the reason I will post it here, in case someone has the same problem
