Open Excel File doesn't work

[Rüdiger Römpp]

Plugin Manager is installed, I can open the previous view an click to "open with Excel 2016", I see the following windows but nothing happens. 

The feature works 2 weeks ago ?

We had a similar issue and found out that a security certificate on the browser (Citrix Environment) was updated and not having the necessary certificates for this action. Maybe something similar here?

thank you for your feedback.

We don't habe Citrix.

After some tests yesterday I find out, that it have to do with diaeresis in the name of the link. It works after removal.
