Why I can successfully load Powerful URF on my PC, but I cannot load skin when I copy all files, including appface.dll and URF onto other PC ?

You should purchase a license to get the needed register info to distribute the software which GUI is powered by AppFace.

What components are needed for my software installation package when distribuing ?

Skinable library - appface.dll (240 KB)
The URF skins you used (Each size is about 30 KB)

I want to distribute a software which contains powerful URF skins after registered, need I pay more for it ?

No.

When distributing, my program load skin successfully if run it directly in explorer , but faild if run it with a shortcut , why ?

Please ensure you have set the right value for the shourtcut "Start In" item .

(Right click the shortcut -> Properties -> Shortcut -> Start In )
