Get rid of popup

[MichiFr]

Hi!

running SAP GUI 7.70 on Windows 10, every time when opening a PDF document from GOS tools I see the popup below (sorry for German language but I guess you get the meaning of it).

How do I get rid of it? FYI, on this Windows installation, Adobe Reader is the default viewer for PDF files, Foxit is installed but not the default viewer. At least this is true when opening a PDF file in Windows explorer.

I do not see this popup here with GUI 7.60 and MS Edge as default viewer.

Any hints on how to get rid of this popup and to change the default viewer back to Adobe or MS Edge. In Windows preferences Adobe is already set as the viewer for PDF files, so I wonder why Foxit still jumps in.

Thanks,

Michael
