commandline parameter for screenshots not working

[Number_1]

Hello,

I´ve changed from xn classic to xn mp because it should be more modern...

Trying to create screenshots to work with a keyboard-shortcut and without starting xn mp first.
This has worked with xn classic perfectly but I can´t get it to work with mp.

If I look at about dialog/command, it seems there is a command prompt for capture.
How can I get it to work?
To mak it short: only a shot from the desktop with numbering (_01_) has worked. I can´t I make a shot from an active window and with correct naming (example screenshot_01_date.png)

I´ve tried making alias on windows dektop, rightclick/settings and paste command line parameter as in xn classic:
"C:\Program Files (x86)\XnView\xnview.exe" -capture=window,C:\Users\XXX\Pictures\Screenshots\screenshot_##_$.ext -> works only in xn classic

of course changed the path to:
"C:\Program Files\XnViewMP\xnviewmp.exe" -capture=window,C:\Users\XXX\Pictures\Screenshots\screenshot_##_$.ext -> nothing happens

also tried
"C:\Program Files\XnViewMP\xnviewmp.exe" -capture=fullscreen -fileoutput=C:\screenshot.jpg (to keep it simple) -> nothing happens

"C:\Program Files\XnViewMP\xnviewmp.exe" -capture=desktop,<output_filename> -> opens shotly xn-mp but no screenshot saved anywhere
"C:\Program Files\XnViewMP\xnviewmp.exe" -capture=desktop,<C:\Users\XXX\Pictures\Screenshots\screenshot_##_$.ext> -> same here
"C:\Program Files\XnViewMP\xnviewmp.exe" -capture=desktop,C:\Users\XXX\Pictures\Screenshots\screenshot_##_$.png -> yeah works but naming without the current date and only from desktop - no option for capturing a window??

Thanks to your detailed description I can reproduce the problem.

Thank you Pierre - much appreciated
I will have a look for the next updates and see if it works...

In the meantime I found out to get a screenshot saved (and not only in clipboard) only with Windows11 snipping tool - which is comfortable too.
(Thats the first time since I´m using Windows that you can create screenshots and save directly with ease!)
It has not worked first despite correct settings so I´ve searched for alternative solution with xnview. Now suddenly it works for me so xnview is not absolutly necessary here but nice to have.

For those who cares:
Solution with snipping tool is:
Screenshot shortcut for active window -> print key or Win+Shift+S (select window in toolbar and then click in window)
Screenshot whole screen -> Win+printkey
-> directly save (not only copy to clipboard) ->Snipping Tool Settigs/screenshots auto-save: set to on
-> maybe also necessary? -> Settings/Accessibility preferences/Keyboard/ print key für screenshots: set to on
(maybe names for path and settings may differ because different language)
