IDXGIFactory::EnumAdapters() does not return any adapters

I'm developing an DirectX11 application. During initialization I enumerate the available graphics adapters as described here.

Now, for one of our customers the number of available adapters appears to be zero: EnumAdapters(0, &pAdapter) already returns DXGI_ERROR_NOT_FOUND.

How is this possible? Shouldn't there always be at least one graphics adapter available? The computer has a graphics card with newest drivers installed and the display is working.

Note: Our application actually uses SharpDX but the procedure is the same. The failing equivalent is GetAdapterCount() returning 0.

Note that with Windows 8.x you would get the "Microsoft Basic Renderer" adapter in 'safe-mode', which is essentially WARP + a legacy VGA output driver. See this post for some implications.

I'll answer my own question:

As it turned out this problem occurred when our customer tried to run our application in safe-mode because of another unrelated problem. In safe-mode the graphics driver isn't loaded and hence there would not be any adapters.
