Thanks for suggestions, soybean.
To be perfectly honest, I've wondered why I have Adobe Reader - it was installed ages ago and I changed to Foxit after some problem ( I think that involved Macromedia somehow). Anyhow, it's now uninstalled and I have downloaded Macromedia Flash Player 8, as you suggest. I have CCleaner.
I still can't find Macromedia listed in Programs and Features. or anywhere else.
