For those who have older systems and are experiencing a Unity bug, this may be due to the launcher using DX12, but don't worry, here is a possible solution.
- Go to the location where you extracted your game launcher.
- Right click on "Amorous 2 Launcher.exe" and click "Create Shortcut"
- Right-click on "Amorous 2 Launcher Shortcut.exe" and click "Properties"
- In "Properties" go to destination and at the end of the .exe" add a space bar followed by -force-d3d1, I'll leave the code part for you to understand ""D:\Download\Amorous2Launcher_Win64_v1.0.6\Amorous 2 Launcher.exe" -force-d3d11""
- After setting this property, your launcher should probably start normally.
- After installing the game in the launcher you must find the .exe of the game that is stored in AppData>Local>Jasonafex Games>Amorous2Launcher/Amorous 2
- When you get to the game's .exe, you will do the same steps 3-4, then the game will probably open normally.
