I installed Magento 2 with sample data and NO extensions so far. Now I wanted to install a bought extension and in the installation-guide is a pointer to System -> Magento Connect -> Magento Connect Manager. But under System there is no Magento Connect.
So I searched a little bit by myself and found a hint under http://192.168.xxx.xxx/Magento/downloader should be the side I am searching, but there is only a "404 Not Found"-Site.
Under System -> Integrations I found a point where you can activate some things. So I tried and activated the point "Available APIs" ->
System Magento Connect Connect Manager Package Extensions
But even after a relog as Admin, there is still no Magento Connect to see under System. Where could it be?
