So yesterday I just bought and downloaded beamng, however when I downloaded it windows couldn't read it. The file was a file extension, also when I installed the tech demo you are supposed to press run but there was no run option. Thanks for your time.
I believe this is a known problem with internet explorer not downloading it as an .exe. You should be able to add the .exe file extension and run it just fine.
Just changed my username from bunnzzz to bunnns. The fix you guys suggested doesn't work for me,thanks for trying. - - - Updated - - - I fixed it! - - - Updated - - - If you get the same bug as me just do save as then rename it to beamng.exe
