In my Dutch version op D-Opus 12, I want to replace Windows with D-Opus 12. This has not been activated when installing, so I looked how to arrange this manually. This is why I bought D-Opus...
At FAQ I learned, I shoud look at:
< Settings -> Preferences / Launching Opus / Explorer Replacement >
But in my < preferences > menu (not under settings, by the way) I don't see a category called 'launching D-Opus' or the like.
It opens with 'Image', then 'manipulating files' etc.
Very clear.
I remember I certainly read the comparing table you mention. And I decided that almost all extra 'pro' options are way beyond my layman's needs and capabilities ;-). But indeed, I now see that Windows replacement is one of those, i.e. not included in the Light-version. A pity.
But thank you for explaining. Bye!
