Inno Setup + Node webkit app exe is not showing app icon in taskbar

Question

I have created myapp.exe (the version of app that runs directly on double clicking) by binary copying myapp's code into nw.exe. This myapp.exe runs with proper app icon in task bar.

However, when created installer through Inno Setup and then run the installed copy, it runs with default node webkits icon in taskbar.

Here is my script of Inno Setup:

[Tasks]
Name: "desktopicon"; Description: "{cm:CreateDesktopIcon}"; GroupDescription: "{cm:AdditionalIcons}"; Flags: checkedonce

[Files]

Can anybody tell what am I missing here?

Answer 1

I observed that the MyApp.exe which I created by binary merging my code with nw.exe, was having nw icon for file in explorer.

Through Resource Hacker (recommended by nw community itself), I changed that Icon to desired customized icon. Then I created the installer through Inno Setup and it started showing the same customized icon in taskbar when I run the installed copy of MyApp.exe.

Not sure if this is standard way for this problem. I would appreciate if someone can guide me on this.

Thanks!

Yes, you’re meant to change NW.EXE’s icon with a program like Resource Hacker and the compile your program for the change to take effect. Inno setup then just zips all your stuff so it shouldn’t have any effect on your executables’ icon.

For future visitors;

The app icon and the icon on the taskbar are different. As stated previously in nwjs community and answers, you can use tool like resource hacker to change the .ico of the executable. But the icon that shows on the taskbar is actually picked up by package.json which should just be a standard png.

"window": {
  "icon": "images/my-icon.png"
}
