At job, I use Opus from USB and I create shortcut X:\DOPUS.exe to Desktop.
Can you replace the Opus 11 icon by the new one ?
You can change shortcut icons to any icon you wish via right-click, Properties, Change Icon.
Yes, of course.
But why not add the new icon in dopus.exe directly.
The main exe icon change was for the taskbar on high DPI systems, but I don't think the launcher exe is ever shown on the taskbar, since it just launches the main exe, so we left it as-is.
