A family of Microsoft word processing software products for creating web, email, and print documents.
See some of my initial posts for the use cases - if you are trying to debug. With all due respect, I think we are in a loop and we are not making progress.
It fails in Office 2016 also. It is only with Office files (e.g., not pdf). The files must be on OneDrive in order to fail (e.g., it is fine on a local drive for me).
As reported earlier, the key, I would think, is to hover over the vti link in the popup, You will then see an attempt for a "shtml" file. I would start with that as a source of the problem. Again, the popup is a problem but the link on the popup seems like a great clue - hover.
