I have just installed ArcGIS Earth 1.7beta and received the following error on startup
DirectX failure D3D11CreateDevice code = 0x80070057. DirectX device creation failed
I have ran the DirectX Diagnostic Tool and found I am running DirectX 11 with all features enabled.
Any ideas what could be causing this error?
I also had this issue when I tried to run ArcGIS Earth in an almost clean Win7 machine. After installing some updates that Windows recommended, then ArcGIS Earth works well.
