A few months ago, I don't remember when, but Flash Player stopped working in
Internet Explorer (SP2), this was probably because of the update to Flash
Player 9. Now, when I try to install it, it replaces were the Flash movie and
version information is with a " symbol. Please look at the picture:

I have no idea what the problem is, but Flash Player works with all other
browsers. My security levels on IE are correct according to the Adobe's support
pages and I'm on an administrator account. This only started happening a couple
months ago!

See this Adobe Technote to solve your " problem.
