I forgot it was integrated in Win 8.1 and when Secunia said I needed to update it manually, I removed it from add remove thinking I would reinstall properly.
It is in control panel>programs and features and videos play. Also I tested it at Adobe and it seemed ok. Is there a way to get it to reappear in add remove shy of system restore or Macrium image?
Because it worked in MSIE and showed in the control panel I knew it was not removed.
I tried it in Chrome and it was ok so I tried FF and it was there videos would not play and prompted me to install it which I did. It came out fine but had a McAfee feature tagged along. I used the uninstaller and we seem to be ok now. There was no indication McAfee was involved to uncheck and I preceded my search with MG for Major Geeks which usually is clean.
it's exactly the same installer for adobe flash player as adobe reader peter, so that's where you missed the tick box and how mcafee got installed on your pc and needed you to uninstall it.
glad to see you figured out it was only firefox that needed the flash player and as soon as you installed it, it showed up again where your used to seeing it, in add/remove programs so answering your own question.
not ever used win 8.1 myself and i didn't know that so thanks for the info.
