I am not sure why CopyFile is failing. Below is code snippet. Can you help me debug? copyfile fnc returns Zero. permPath is Temp dir loaction on C:\ and I checked it is fine.

if ((hFind = FindFirstFile(L"*", &fd)) != INVALID_HANDLE_VALUE)

            if (wcscmp(CAU_PKG_SIGN_FILE_NAME, fd.cFileName) &&
                        wcscmp(L".", fd.cFileName) &&
                        wcscmp(L"..", fd.cFileName) )
                        wstring newFileName = permPath + wstring(fd.cFileName);
                        if (!CopyFile(fd.cFileName,(wchar_t*) newFileName.c_str(), FALSE))
            while (FindNextFile(hFind, &fd));

Run it in debug mode, and look at the value of fd.cFileName and newFileName

You should not need to use the (wchar_t*) cast, and I recommend that you remove it.
It only serves to prevent the compiler from doing it's job in type checking.
