Image doesn't open from Windows Explorer

[ashwin]

XnView Version 1.3.1
OS Windows 10 21H2

When I go to the Windows Explorer and try to open an image, nothing happens. If I open XNViewMP and then open the image, after navigating to a directory it works fine. This was working in earlier versions. Please fix this.

In most cases the picture files are not correctly linked with the standard program.
Check in windows control panel, if xnviewmp is your standard picture viewing app.

Please check, which file extension the picture file has.

Sometimes other programs like web browser or other applications overwrite the standard viewing program.
