The SVG viewer and NGraphviz can causes some common failure that are easy to workaround, i.e. I don't plan to fix them soon ;)

1.

 Diagnosys: The first time you run the Adobe SVG viewer, a copyright dialog pops up. After that, you will hit this failure.
 Workaround: Close Reflector and rerun. The dialog is gone and everything works fine.

Object reference not set to an instance of an object.

2.

    Diagnosys: You don't have the necessary C++ libraries on your machine to run NGraphviz.
    Workaround: make sure msvcp71.dll and msvcr71.dll are available.

The specified module could not be found. (Exception from HRESULT: 0x8007007E)
