Can't find flash ?_?

Each time my vista computer updates a new version of adobe flash, it can't
play my flash screensaver. (yes, I know most modern screens don't need
screensavers anymore, but I have an old bulky one. Besides I personally like
to look of it.)
I bypassed the problem that vista 64bit can't play 32bit screensaver by
playing it through my anti virus scanner. it apparently can play any
screensaver I like. But somehow after the update it does not work anymore.

This problem also occurs on my other windows vista (32bit) computers. those
do not need to run the antivirus scanner to play the screensaver.

Does anyone know how I can get windows find flash again? Flash on internet
websites do tend to work properly.

Grt,
