I have some games that run in Net framework 2.0...

What the difference with net framework 2.0 and 3.5 in games?, If the game run in Net 2.0, there is a way to switch to 3.5?, or jut i need to update/download to net framework 3.5?

The game is Railworks 2010 ( So far the best train sim ) i`be asked in steam forums and RW forums , but i dont gent any answer

Any advice?

Why don't you just update? .NET 3.5 has some new things, if the game uses 2.0, it would still run, just like with .NET 2.0, maybe even faster.

thank you, actualy i`m installing all net vercions and installing 3.5

3.5 includes 2.0, so you don't need to install both.
