To download and install adobe flash player, I first have to use the exe. to
uninstall all old versions. Once done I install and everything works fine.

Unfortunatley, the next day I have to repeat the process to get it to work
again. Every day!

Anyone know what could cause this?

I have the same problem. After a couple of days, I am prompted to reinstal
Active X 9, but that doesn't work. I first have to uninstall, then reboot, then
reinstall. What a pain. Why is this happening and how can I avoid it? Is
there a relationship between the Adobe reader version anf Adobe flash? I was
using Adobe reader 5, but now I upgraded to Adobe Pro 6. Maybe that will solve
the problem. I am using Pro 6 on my other computer and there is never a
request to reinstall.

:disgust; Same fricken problem here and I'm sick and tired of it. Why can't
they offer a real solution.

The only solution I have not tried is a change of the registry at the risk of
screwing things up even worse. Why don't the company responsible for the
problem offer a real and easy to implement fix.
