Diagnostic utility: vdDiagnostic
This utility produces the vdDiag-LOG.txt with the VDF
dlls/tlbs/ocx installed in the system. It also produces a
vdDiag.CAB file that you should sent to us if it is asked by our
support team.
A new dll named vdfext.dll is available for developers and their customers in order to be able to see the preview image of a VDML, *.DWG or VDCL file in the windows Explorer as thumbnail. This dll must be registered in the system's GAC. Note that not all VDML, *.DWG, VDCL files contain a preview image inside them, as the developer has the option to add or not such a preview image during save. If the file doesn't contain a preview image then a default icon is shown. See article.
