The problem has been resolved at last. The comments from Mr fixit today were 'This is the dirtiest PC I've seen in a long time' It had over 4000 Malware items and many other things to remove. His advice to potential upgraders is to wait until the free download offer period is nearly up before you download it, by which time Microsoft should be shipping a much improved version. Then make sure the PC is clean.
He still had an issue with IRIS. Command box or Drag and Drop. Not both but he soon sorted that.
Never the less I appreciate all the help with this.
