Application icon size issue in Explorer

In Explorer, my app icon view remains small while scroll holding ctrl, but icon file view is scaled large.
Platform Toolset: VS2010

Sorry, don’t understand… can you explain more clearly what you mean?

My icon file is produced by icon maker app. When using it in my juce app, app execute file always shows small icon in Explorer thumbnail view. But icon file show large size in thumnail view.

If you’re using your own icon maker app and the icons aren’t working, how is that a juce problem?
