Old icons cached? - New icons are not consistently used across

[distributev]

• Version: "electron-builder": "^19.27.1",

• Target: build -w --ia32 (Windows 10 64bit)

It seems the same (or similar) issue was raised here - #840

I changed all the icons with new icons I regenerate the exe file 3 or 4 times but the old icon (even if meanwhile I re-generated 3 or 4 times with 4 different icons) still show next the my App.exe in Windows Explorer. When I double click and launch the app the correct / new icon is showing in task manager.

Here is a screen-shot

Do you use installer to install app and launch or run it directly?

Just restart Windows.

[distributev]

I run the app directly. I have no intention to create an installer I want to create a self contained app.

I restarted Windows and the behavior is the same I see the old icon near the App.exe and the new icon when the app is started and it's in the task-bar.

Do you have an idea why the old icon is still being used?

[develar]

Consider to use portable target if you want self-contained app.

[distributev]

I already doing that - this is an extract from package.json

"win": {
"artifactName": "${productName}.${ext}",
"target": [
"portable"
]
}

Can this be related with the cached icons?

[develar]

Do you mean that on desktop do you see old icon of portable executable?

[distributev]

Yes the PortableApp.exe shows the old icon in Windows Explorer.

If I double click and launch the new (correct) icon is coming in Taskbar.

[develar]

Possible Solution — portable should refresh desktop on launch.

[distributev]

I don't understand what you want to say here. I launched the exe many times and Windows Explorer icon does not change (refresh) - the old icon will remain. Windows was restarted also.

Ahhh the old windows icon cache issue. I've dealt with this before. From memory I used a combination of these hacks:

I agree, Windows is a pain ;)

I discovered today Electron (or Windows) is caching the icon based on app ID.

In my electron app I set app ID here

app.setAppUserModelId('com.myco.myappname');

If I changed that app ID when I changed the icon, the cached icon went away
