Epub 3.0 Not working in ADE 4.5 with windows 7 OS

In window 7 OS system I've installed ADE 4.5 version. When I open Epub 3.0 file in this version It shows "Unable to open", if I change the same file version into Epub 2.0 in OPF I can be able read the file in ADE 4.5 no errors shown while opening this file.
