Some problem has occurred though, this error did not happen until I ran Word 2003. Thanks for the hint I will try your registry solution if I get my admin to do it, although it apparently is only geared to suppress the nasty Word dialog not to fix the Robohelp error.
Whilst you were clear I must admit I was thinking of a different scenario.
I would not expect importing to give any issues no matter what the Word version but certainly not if 2010 was the last to run. I wonder if a Word 2010 repair would fix things?
The error message is not a RoboHelp error, simply one that Word throws whenever the version is switched. It would occur simply with opening Word.
