DWG 2007 no longer opens after upgrade to Microstation SS10 (08.11.09.919) shows "bad file" error or contact administrator. Creating new empty file with delivered DWG 2007 there are no issues. There was RealDWG 2014 left after upgrade uninstalling it doesn't help. SS10 installed RealDWG 2016 (08.11.09.919).
Installing RealDWG 2016 from downloads(08.11.09.852) resolved the issue. Seems delivered library is not the latest even that number is higher.

It appears this issue with the RealDWG version in MicroStation V8i SS10 was raised as a new "Defect 1097925: Unable to open DWG R2007 format" by Rene van den Brink
