WIA Automation not working on windows XP

Question

I have used vs2010 and silverlight 5 to access scanner in web browser. It was work on windows 7(32 and 64bit) machine perfectly.
At same time i was not able to get either function to work  on window XP(32 and 64bit) machine.. I found that XP could not read WIA. When i going to create object like AutomationFactory.CreateObject("WIA.CommonDialog")), i got error as "No object was found registered for specified ProgID".

My code is,
                try
                {
                    using (dynamic CommonDialog = AutomationFactory.CreateObject("WIA.CommonDialog"))
                    {
                        dynamic imageFile = CommonDialog.ShowAcquireImage();
                        if (imageFile != null)
                        {
                            if (!Directory.Exists("D:\\ScanImage"))
                            {
                                Directory.CreateDirectory("D:\\ScanImage");
                            }
                            string filePath = string.Format("D:\\ScanImage\\{0}.jpg", Guid.NewGuid());
                            imageFile.SaveFile(filePath);
                        }
                    }
                }

Thanks in advance.
