I have already tried the fixes that have been shared. When I try to manage add-ons, the list says they are all enabled. Apparently, there is supposed to be a choice between running IE with add-ons and without. My only choice at the start menu right now says "internet explorer (no add-ons)". None of the help fixes the problem.
I don't know why I've never been able to go to a restore point. I have AVG anti-virus. When I go to a restore point, the computer goes through the moves but says it was unable to perform the action. It says that there is a restore point, but was unable to restore the computer to that point.
Thanks for the efforts.
I downloaded AVG PC tune-up and now get a message that internet explorer is running with add-ons disabled. I contacted AVG but they are useless.
When I go to manage the add-ons, they are all listed as enabled. I even tried resetting IE but it didn't help.
I can't look at youtube and lots of other things now. How can I get the add-ons to work again?
I have Windows XP.
Thanks for any help.
