Hello everyone, I made a Managed DirectX game in our company and I would like to start selling it. The problem is with Windows Vista. Installing managed directX9 on a system that has directX 10 (Vista) was impossible to me because a newer version of directX is already there so the directX installer doesn't install. (And there is no Managed DirectX 10 available) The managed DirectX game only works on Windows Vista when I put the following Dlls in the same folder of the game's EXE. They are dlls of: Microsoft Managed Direct3D Microsoft Managed D3DX Microsoft Managed DirectInput Microsoft Managed DirectSound Microsoft Managed DirectX Helper Classes Their file names are: Microsoft.DirectX.Direct3D.dll Microsoft.DirectX.Direct3DX.dll Microsoft.DirectX.DirectInput.dll Microsoft.DirectX.DirectSound.dll Microsoft.DirectX.dll N.B. These files are automatically detected by the software deployment tool of visual studio as "Detected Dependencies" and added to the installation. Do I have to exclude them or is it legal to leave them to be installed to the folder of the EXE on the user's computers? If I have to exclude them, Is there any other solution? Thank you very much.

Thank you very much jollyjefers. you really helped me about the legal stuff but seems that I still have no clue of how to install managed directX9 on vista which has directX10 or any other solution. Does anyone have any clue?
