Often inner exceptions is a very common problem for converting words documents in PDF via Aspose.
It can be due to some reasones like:
- 2013 MS Word office.
- Some complex elements in word
- Old version of Aspose.Words.dll.
Solutions:
- Try to update Aspose.Words.dll to new version. If it's still not working - write to aspose forum, and this error will be fixed in new release.
- Check word document itself. may be you can find something thac call this inner exception, than try to remove it and check again. If this is acceptable of course.
