This is important information!
In such case it looks like a proper RealDWG libraries are not installed or the older version of them is configured / used.
You can try this:
- Start MicroStation.
- Open any DWG, e.g. some from DWG files delivered in Examples / General dataset.
- Open key-in dialog and type version.
- In Message Center an information about MicroStation and used DWG libraries is displayed.
Try it at both computers and you will see, if the version of used RealDWG libraries are the same or not.
With regards,
