FastCAD32; "Can't find xpDWGCvt.dll"

I recently installed FastCAD 32bit on Windows 7 32bit operating system. It installed successfully, but every time I start FastCAD program it complains that xpDWGCvt.dll is not found. However, if I just click OK button on the message box and ignore it, FastCAD program starts up as normal and I can do everything I need to do with it.

I looked on the internet about xpDWGCvt.dll file, but there is absolutely no search result for the DLL.

Does anybody know what it is and how to fix my error box on my windows 7 32 bit system?
