CCleaner used to run but now it disappears once run is clicked. It seems the problem came around the time Microsoft monthly downloads were installed. Not sure if it was a few days before or after. I remember seeing a list of questions I should answer to help with this issue but I forgot were I saw them! I also do not know why some passwords or cookies are not automatically entered or why certain web sites don't recognize me and ask the secret question only I know the answer to(this happens after I ran CCleaner.)
Is help available? I did not try and un-install and re-install CCleaner.
