I don't know why you're trying to piss people off, are you some kind of mole working undercover for GoG?
You assume nobody has summited a ticket, and, as a matter of fact, many of us did.
But in this case, the problem lies with the developer, not with GoG support. If the developer doesn't provide the installation packages, there's nothing GoG can do.
So, we post here in this sub-forum, because we are aware that the developer reads it. (and sometimes even replies)
Their installers have always had GOG plastered on it, why on earth did you even consider game devs would waste their time on that bullshit.
Check the other threads please, then you can understand. A clarification would be welcome, but until then there is no need for you or anyone else to make unreasonable posts. You just harm the rest of us who wants to be taken seriously.
