I downloaded the file but idk wich one is the game. There are nwjc.exe and nw.exe. And why people says that nwjs archives are dangerous?
Choose nw.exe
Paccsu explained it on 0.664 update log
Idk if it's a new RPGM thing or Paccsu wanted to do it, I'm not an expert in game dev
nw.exe starts the game. I updated the engine so the exe file changed names.
