I have no shell commands in DOPUS (latest x64 bit version). No Open With ..., nothing. Provided is what it should show in a screen shot attached.
Is Preferences / Miscellaneous / Windows Integration / Hide Windows items on file context menus (shift overrides) turned on? (If so, turn it off.)
As usual for what I paid for the app I get more back into intuitive people who know what they are talking about.
Know a way to put everything script into doous?
Is that a genuine question 
?
