I did that earlier but the same error in egnyte popped up. How do I see if it is Adobe Reader or the build-in opera reader? The pdf interface with and without activated "default application" looks identical. Btw. I did restart opera after ticking/unticking the box.

Hi,

Egnyte requires me to use adobe as a PDF viewer. Is there a way to make adobe reader the defaule PDF reader in opera 45?

Frank.
