I have vista os and having trouble playing videos in various websites. I get the message you need to install Flash. I install it and it gives me "successful installation." I go back to the website after re-opening my IE8.0.6001....and get the same error.
I have looked in the "add-ons" for IE and I have Flash 10.0.22.87 (installed back in 2/2/2009) and here we are 7/8/2009.
I rebooted etc. nothing works....
You might do better in the flash player group
