Found this in the event viewer from earlier today, probably the first time I tried to install: Product: "Bing Maps 3D. The application tried to install a more recent version of the protected Windows file C:\Windows\system32\xinput9_1_0.dll. You may need to update your operating system for this application to work correctly. (Package Version: 9.10.455.0, Operating System Protected Version: 6.1.7600.16385)."
I went to Windows Update and got the latest (I don't like Automatic), but now the install craps out even before the download.
