The log is attached.
.NET 3.5 is installed (see attached file dotnet.png).
I've got this pink "artifact" in the main menu (see attached file yr.png) - the exit button is also missing.
I get the error regardless of choosing Skirmish or CnCNet, but after the error when I choose CnCNet, the app crashes and I get a .NET Framework unhandled exception (see attached file ue.png for details).
As you can see in the details, it says that "game-dir"/INI/Default.ini couldn't be found, so I went to game dir and found out that, compared to the installation on my other machine, the 3 folders; INI, Map Renderer and Maps were missing. So I tried to copy the folders from the other machine and I got a little longer. In CnCNet I get to the lobby, but it's like the "artifact" from the menu is still there, now it's just black. When I choose skirmish I also get a bit longer, now I can choose map and all that, but when I want to start the game, I get another error - see attached file "error.png". After that, I tried to copy over gamemd-spawn.exe, but get a new error - see "yr_error.png".
I have tried to install the game in a folder in My Documents - it's still the same. The 3 folders and gamemd-spawn.exe aren't created there either.
