    Hi again

    i did the above step but it did not solve my problem the first time
    i restarted the system and did it a gain
    nothing changed
    but by searching in the web i found another code which is listed under HKEY_CLASSES_ROOT\AppID
    i deleted it and it resolved my problem

    i tried to find that code
    coz i did not save it
    but i could not

    thankyou anyway
