Application is published successfully through vWorkspace Management console and its icon is retrieved properly. However, when user accesses list of published applications through Web-IT or AppPortal, specific application's icon is missing or show question mark icon.
Non-standard icon properties, unsupported color depth.
Issue can be caused by 32-bit color depth of icon. Additionally, icons are usually embedded into application's EXE file and there's no easy way to replace it. As alternative, icon can be retrieved from application using 3rd party extraction tool, modified so it'll have 8 or 16-bit color depth and size of 16x16. Then such icon can be assigned to the published application through vWorkspace Management console.
