According to this thread, one has to set "servoy.branding.webstart.loadinglogo" to provide an own icon for the windows shortcut that Servoy creates when a user runs a smart client the first time:

As Windows 7 shows the best results with 256x256 Icons, I asked a fiverr artist to create a 256x256-ICO-file for me. That file I provided into "servoy.branding.webstart.loadinglogo".
However that ICO-file Servoy did not take.
I then provided a 256x256-PNG-Icon, and that was somehow converted/downsized and did not show sharp.
(To force Java to create the shortcut new, it is necessary to go to Java Control Panel and delete the temporary Java Files there, a sole deletion of the shortcut on the desktop will not force Java/Servoy to create a new shortcut.)
So my question is, with what file type and resolution do I get the best result for the creation of the windows shortcut icon under the current Windows 7 OS?
