Hi, please can you educate me? I'm looking at a laptop for someone, Dell Inspiron 1545 . The laptop is running windows 7. As soon as I boot it up, I get (on the desktop) the error message, 'could not load file or assembly 'sortkey.nlp' or one of its dependencies. The system cannot find the file specified'.

Please can you possibly advise me on this? To the very best of my knowledge nothing has been deleted, changed, or modified. Please can you help me out? Thank you for your time.
