How to get Next Car Game demo for Linux

I went to nextcargame.com to get the demo, and downloaded it. I set it to allow executing file as a program in properties, and opened it with Wine Windows Program Loader, and it installed fine.
When I start the game, it opens up fine and the title screen opens up for the game, but then it says: The Program NextCarGameFreeTechnologyDemo.exe has encountered a serious problem and needs to close. We are sorry for the inconvience. And then it forces me to close.
I tried to uninstall it and reinstall it, but it said the same message.
Did I miss something, or am I doing something wrong?
