reshacker.exe -addoverwrite 7z.dll, 7z.dll, sevenz.ico, icongroup,101,1033 PROGRAM OPERATION SOURCEFILE, DESTINATIONFILE, RESOURCE.ICO, ICONGROUP/ICONDIR that's what i used in the past... something logical basically the ability to directly replace an icon from the 'icon directory' ie.. feel free to pm me test versions etc i don't know much about programming, but the ability to drag a .ico file directly into that resource to replace it would be a cool addition too if that's possible in the future
