Dear @Teekin,
i-MSCP is not a game or a software you just "double click" and it starts.
It's a Control Panel for web hosting services. Now, if you want to offer this kind of service, you have to do it in a professional way, so you have to be a professional Linux system administrator first. Then you can begin to see how i-MSCP really works.
Eventually if you need such software in your enterprise for internal use, you have to install it on your server. If you are not a Linux professional, I'm pretty sure there's someone who can manage that for you, so a professional, so someone you have to pay.
If you don't know how Linux works (and Linux components also like postfix, fpm, apache, etc.) there's plenty of documentation in the whole internet world, or if you prefer, there's plenty of courses you can follow in order to learn end finally to understand what you are doing.
Regarding @Nuxwin, he Always gives the right support for everything regarding i-MSCP. Linux school is not his job. He replies perhaps in particular ways sometimes, with his sarcastic words, but that's just his way to be... just Accept or Decline. Your choice...
