It is posible that you updated your Windows 8 to your fantastic new version of Windows (Windows 8.1) and then open Unity to continue working in your game and in that moment...

Crash! Yes, Unity crash and you say: "This should be a problem, but let's go to try again...", then you try the compatibilty mode, but nothing... Unity doesn't want to work!

Okay, and what is the solution? Downgrade my Windows? No! It is not necessary, you only need to follow these three steps and the problem was gone to the past:


  1. Right-click over the shorcout to Unity and click in Properties
  2. Search for a textbox which has text like this: "C:\Program Files (x86)\Unity\Editor\Unity.exe"
  3. Replace that text for that: "C:\Program Files (x86)\Unity\Editor\Unity.exe" -force-d3d11 and close
And it is done! If you try now to open Unity, Unity will work without problems and it shouldn't crash.
I hope that it will work for you!
