[quote="Gardhul"]From Iconpackager, select under TOOLS menu, "Repair shell icons"; then add "DOpus.exe" at the presented programs list, then close the window. That's all.
Now, after applyed a new icon pack, just close DOpus from system tray icon, and re-launch it. NOTE: You DON'T NEED to force repair icons from Iconpackager for each pack change. Just close DOpus from systray and re-open it.[/quote]
