Did you try the procedure for manually uninstalling/unregistering the Flash Active X Control?
I would like to get the Flash Player from Macromedia off of my Win 98 machine. The ads that Flash support are very intrusive and frustrating when browsing. I have gone to the Macromedia site and used their uninstaller, but it does not remove it entirely. Something is still on the unit that allows the ads to still splash across the screen. I keep using the "uninstaller" from Macromedia and removing the folders from the Windows directory, but they keep reappearing. Something is permitting the player to play the ads when I visit certain sites. Any ideas or solutions regarding this problem?
