Hello all! I have downloaded Unity FREE and have been playing with it. Am most impressed. However, Unity requires .NET 4 framework which for some reason knackers my PC up when it's installed. .NET 4 came with the UNITY download and once installed I found I couldn't open Unity. After a bit of faffing I uninstalled .NET 4 and Unity would then launch properly - although I can not edit/create scripts as this requires .NET4. Just wondered if anyone else has/had this problem? thanks R
