Hello, last years I play FS9 on W7 32b,DirectX11 and sweetfx. Because of a virus I change and now I have W7 64bits sweetfx and always directx11. But whent I start the game I have a message:"MSF can not run because the version of Microsoft DirectX installed is not compatible.Reinstall DirectX 9.0 etc..." If I remove the d3d9.dll from the main folder of FS9 the game runs, without the SweetFx improvement, of course. I reinstalled DirectX 9 but it's the same thing.Does anyone has a solution? Best regard. VinSim Sorry for my english

Try running this program and then restart your computer: https://www.microsoft.com/en-US/download/details.aspx?id=35 If that doesn't work you should try removing SweetFX, deinstalling the game, removing everything else left in the game directory and then reinstalling the game again.

Hello thank's for the answer. But yesterday, I don't know how, I've tried again and it's OK now... it is a computer mystery... I did not change anything... Thank you. VinSim
