Internet Explorer 11 opens PDF-Files downloaded from Internet always in the browser and not native in the Adobe Acrobat Reader 2015
Hello Community,
here we have the Problem, that the Internet Explorer 11 opens PDF-Files, downloaded from Internet, always in the browser and not native in the Adobe Acrobat Reader 2015 (Version: 2015.006.30355). Even though the following option is not enabled. This error can also be reproduced in Adobe Reader DC and Adobe Acrobat Reader 2017 (Classic). This behavior has not occurred in Adobe Reader 11.0.22.

Is anyone aware of a solution to this problem?
Thanks in advance!
