I got this error report from windows after installing latest flash player version. after test it looks like player is not installed (no plugin) but in cofiguration, flash player, version it says version "11.8.800.84" for plugin and "not installed" for activeX version.
running vista, safari (needs player to operate movies etc) and incredimail(needs flash player to operate, so no email at the moment)
I tried uninstalling/reinstalling etc.. nothing works
downloaded shockwave, same error (no plugin)
I have Flash Player 11.8.800.94 on my VIsta Ultimate machine and it runs in IE, Firefox, Opera, Chrome and Safari. The ActiveX version is ONLY for IE and Outlook.
Download the Adobe Flash Player offilne installer directly by clicking one of the following links.
Run both of those and see if it helps.
