Hi Feda,
Thank you for your reply.
I downloaded CnCnet and put it where my Dune2000.exe is.
I can launch CnCnet, choose a map and some options like IA, etc. but when I clic on "Launch Game", I have a black screen and... return to CnCnet.
I selected different resolutions, different options like "DirectDraw", etc., but the game does not launch.
I installed the Gruntmods Edition of the game but I have the same problem.
However, when I launch the "MissionLauncher" of this edition, I can select a mission and play it.
Do you know why does this happen ?
I have a good PC (i9, RTX 2080 Super, 32 gb of RAM, etc.) and my screen displays 1080p natively.
I wish I / we could fix this.
Thank you for your help.
Edit : It's okay, I unchecked "Disable Max Windowed Mode" and now, the game seems functional when I launch it in CnCnet.
I thank you very much for your help.
I have a lot of alternative missions to discover (alone and in co-op too), so I am happy.
Thank you for all the work and the help given to the players about this really great game.
