I am running Windows XP, MSIE 8.0. I have installed Flash Player 5 times. It keeps disappearing, or won't even install over Internet Explorer. It stops halfway, and tells me to close Internet Explorer because it can't install with it running. I did that yesterday, and it installed when I started IE again, so I thought the problem was solved. Then, today, I logged on and tried to use Flash Player. It was not installed. I re-installed it, and came to the same block. It will not install while Internet Explorer is running.
