I am using a HP Photosmart 6510 printer on a Windows XP operating system. After starting my computer it starts looking to load HPPhotosmartEssential.msi file but it is missing from the pc. I read somewhere that it could be in the Prefetch folder but it was not there. Now I dont know where is it and I want to like to get the file loaded so that it can open automatically rather than asking for it at each startup of my pc. Any help would be appreciated.
