I have used vs2010 and silverlight5. I can able to access scanner through WIA Object on windows 7(32 and 64bit) machine. But WIA object returns nothing on windows XP(32 and 64bit) machine.
When i going to create object like AutomationFactory.CreateObject("WIA.CommonDialog")), i got error as
"No object was found registered for specified ProgID"
Is there any different between windows XP and windows 7?
Silverlight 4 may support elevated trust in browser on windows XP?
My code is,
using (dynamic CommonDialog = AutomationFactory.CreateObject("WIA.CommonDialog")) 
dynamic imageFile = CommonDialog.ShowAcquireImage();
Thanks in advance
