Installing a Theme in ObjectDock
There are several ways of installing themes in ObjectDock – newer themes use the .docktheme file extension or the .dockzip extension. To use .dockzip files, simply save the theme and use ObjectDock to import the theme. Alternatively, .docktheme files can be run (double-clicked) in order to apply the the new styles for the theme.
However the theme suggested here, the OS X Leopard Dock Pack, is an older file that comes as an old fashioned ZIP file. As such, the contents need to be unzipped in order to be used, and stored in a location where ObjectDock can find them.
With your theme downloaded, browse to C:\Program Files\Stardock\ObjectDock\Backgrounds\Non-Tabbed (note this location will be different if you installed ObjectDock to a drive other than C:\)
This is the location your unzipped theme files should be saved to – either use the Extract command to save them there directly, or copy them out of your ZIP extractor (such as WinZip, WinRAR, 7zip or the native Windows unzipping app) directly into the folder above.
Once unzipped, use the ObjectDock Configure Dock menu to select the theme in the Appearance tab – and your dock is restyled!
