flash player 9 problems

As I read the problems in the adobe forum for flash player 9 has anybody have a similiar problem where it says it downloaded but isn't to be found anywhere. Before I had it downloaded and it showed it in my programs, it tested fine but when it was needed for a program on the net, it told me I needed to download the flash 9. everyone is having problems with this as I have cleaned my registry and used a debugger for this but still having problems with it. will going back to flash 8 help with the situation. I have windows xp sp2 and installed a few weeks ago, google toolbar and upgraded to explorer9. Can anyone help me?
