I’ve had a one-off report from a user of AutoCAD 2009 (actually, it was MDT as part of the Inventor suite pretending to be AutoCAD 2009, which isn’t exactly the same thing) and I’d like to know if anyone else has seen the same thing. His AutoCAD self-destructed and a little investigation showed that the section of the Registry that contains all the settings for that particular release had vanished without trace. This happened again later, but this time he had a backup of the Registry section handy and was able to avoid a second reinstall.  No Registry cleaners were involved.

Have any of you seen this kind of thing happen?
