Well, one of the reasons you might be having a bit of a problem is because the truevision3d.dll is actually a COM typelib.
IF you have MS Platform SDK you can run the tool OLE-COM object viewer to have a better look at it.
Also running the Platform tool "depends" you will also notice that the typelib actually depends on the Visual Basic 6 runtime dll MSVBVM60.dll(*shivers*) and DX8VB.DLL .
That is for TVSDK 6.2, I don't know how it's done in 6.5
