For VDF applications to run correctly, a number of external dependencies need to be in place:

== MSXML ==
[http://msdn.microsoft.com/en-us/library/ms763742(VS.85).aspx Microsoft XML Core Services (MSXML)]

It is currently "unknown" outside DAW what version of MSXML is used by flexml.dll

== GDI+ ==
[http://msdn.microsoft.com/en-us/library/ms533798(VS.85).aspx Microsoft Windows GDI+] is a class-based API for C/C++ programmers. It enables applications to use graphics and formatted text on both the video display and the printer. Applications based on the Microsoft Win32 API do not access graphics hardware directly. Instead, GDI+ interacts with device drivers on behalf of applications. GDI+ is also supported by Microsoft Win64.

GDI+ is used by the [http://www.dataaccess.eu/IframeText.asp?pageid=1670 Graphics Library] from DAW, currently in Beta.

''Note: GDI+ is not officially supported for use within a Windows service.''

Olaeld: Is FusionCharts really an ActiveX control?

To be nitpicking, is FusionCharts really an ActiveX control in itself? It's using Flash, and is not in itself an ActiveX control, right?
