I know it says "extract and run", but there's nothing to run. Normally when I download a Window's version of a game, I see "Game.exe" and I play the game using Wine Staging. However, when I downloaded this game (using the MEGA link), I couldn't see "Game.exe" anywhere. You mentioned anti-virus could have caused it, but I didn't get any alerts, it downloaded like normal. Don't know if this matters, but I'm using a Mac.
ooh u mean .exe? NW.EXE is the name of the executable.
and if u are unsure about uploader fault or ur av fault,i think u can check by open the .rar,check if there is nw.exe.
if there is,mean that it blocked by ur AV (Adult Video) oh sorry (Anti Virus).
but idk,never use AV for 5years+,i only use microsoft security essential for my win7 x64.
different OS and different AV behave differently.so i trully dont know about AV nowadays.
--add: i try to redownload the .rar from mega by uploader,and there is NW.EXE inside.
so i think something must be teribbly wrong with ur PC or AV,maybe the OS?
try to check things..
below are the exe ur asking,and i marked it with red circle(?)
and btw this is the .rar that i just download second ago.
