Hi.
Using dopus 12.0.7 i get this weird error for acdsee which i have never installed. I am moving to dopus internal viewer and want it as my default viewer in opus, system wide is not necessary.
Why is dopus thinking that i have acdsee and how can i return it to default, ie to show pictures in his internal viewer?
I can confirm when reinstalling dopus fresh in default configuration it works normally.
Thanks for the time.
Leo i have enabled "Preferences - File Operations - Double-click on Files: Use internal picture viewer" that error is shown only when i have this enabled, when this is not enabled it opens pictures in Windows 10 photo app normally.
As i said fresh install of dopus and checking that it handles images on double click, working normally.
I think there is some problem in my opus configuration, i have upgraded from 11 to 12 beta and have custom toolbars and hotkeys.
Have you made any changes to and of the Left Double-click events under Settings -> File Types? (Maybe the one for the Images file type group, or the type of file you're double-clicking.)
Yes thanks leo for the idea, i was importing quite a bit of toolbars and custom settings and i guess somebody changed that. Was loooking at file type "images" before normal but didn't saw that there is dopus group "recognized images" 
and there it was open with acdsee ... just replaced with show, working normally, thnx again
