This error:

Capture One error when processing a file

has become a considerable pain in daily processing for me with Capture One Vr 9, (all versions) under Windows 7,8, or 10.  If you have noticed this error in your processing, please reach out to Phase One and let them know about it.  You can read more about the problem in this article I wrote by clicking on this link: Capture One error when processing a file.
