Open With does not agree with Windows Explorer (Win 7)
am trying to get a program to show on right click Open With
it is a png file
i go to choose program, select the program and it does not appear on the list, with or without the Always use checkbox
Windows explorer DOES show the program i seek on the right click Open With
how can i get DOpus to show it?
i already went to control panel, file associations and set it there too
Which program?
Do things work if you set it via Explorer?
yes, Explorer launches the program Snagit 12 Editor correctly
If you change the default in Explorer, does double-click then launch the same thing in Opus?
Or are you just aiming to launch the program as a one-off and not change the default?
Adding a context menu item for it may be the quickest solution. You can usually add one which runs:
"C:\Program Files\full\path\to\program.exe" {filepath$}
to launch a program and send a file to it. (Exact details can depend on each program's command-line syntax.)
will get back to you on yr first question later, that machine is elsewhere
but i have another data point of interest
the machine i am working on at the moment does not have the original problem, i.e. Open With shows Snag It editor in DOpus
this machine has only had Snag-iT 12
the other other machine has Snag it 12 upgraded to Snag it 13, after a while i uninstalled Snag it 13 as it was horrible leaving Snag It 12 installed, does that play into this somehow ?
I assume you have clicked on "More Apps ↓" to expand the list ? 
That's how it is in Win10 at least, i actually forgot what the Win7 dialog was like!
Leo i am really stuck here on this issue and it is becoming a real impediment, on one machine i simply cannot get Snagit to show up on the right click Open With in Dopus but it does show up fine in Windows Explorer
on another machine it is working correctly in both Dopus and Windows Explorer
any idieas how i can fix it ? registry edit or something ?
Adding a context menu item for it may be the quickest solution. See my reply above.
