If you are running Etere DataMover in Windows 2008 Server R2 operating system it is required to install the Desktop Experience windows feature which includes the wmdcore.dll component (i.e. a Windows Media Library constituent used for compressing and decompressing media files).
If this feature is not installed in the system, each time the Etere DataMover application attempts to start, an error message would be prompted.
For more information, please refer to MS Desktop Experience Installation chapter.
