Missing file, installation?

Hi, it's my first installation of Opencart so need some help i cant figure out what the problem is.
I wanted to install the Multi Vendor to my Opencart. So i upload all the files to my account and then i follow this step here.
## Installation
Unzip the zip files to your web directory.
Rename the admin/config-dist.php,seller/config-dist.php and config-dist.php files to config.php.

But i can't find seller/config-dist.php so i did the installation witout this file but now i can't find any multi vendor setting in my admin panel of Opencart.

Please, anyone that can help me out where this file seller/config-dist.php are or how to turn on multi vendor?

/seller/ is not a normal OpenCart directory, so it must be part of your multi-vendor mod. It's unlikely anyone on the forum can help you with a commercial extension, so you should contact the extension developer for support.

Hi, thanks for your reply.
But i don't understand. In this URL
https://www.opencart.com/index.php?rout ... ber=ovicko
The istallation help on this say like this:
Multi Vendor is built on top of OpenCart 3.x thus it inherits all the inbuilt features of OpenCart.
You can easily use the Multi Vendor to create a Marketplace store where both admin and customers can sell their goods and services.

And then it say like this:
## Installation
Unzip the zip files to your web directory.
Rename the admin/config-dist.php,seller/config-dist.php and config-dist.php files to config.php.
Make sure the seller/config.php, admin/config.php, config.php files have read and write permissions.
Visit http://yourdomain.com/install to start the installtion process
Login to your admin end, give admins permissions by navigating to System->Users->User groups (edit) select all and save.
That's it!
You can now access the seller dashboard at yourdomain/seller/index.php

But nothing of this seems to work.

What am i doing wrong here? Does Opencart have Multi vendor?

Opencart has NO Multivendor Function built-on by Default.
You have therefore to rely on the Multivendor Extension Creator,
to eventually solve your Problems, or get a paid Developer to assist.

The link you posted is an extension. It modifies how OpenCart works, adding multi-vendor support. It appears to have issues, though, so you'll need to contact the developer to get support for it.
