Every time I want to watch a YouTube video, I have to install Adobe Flash Player Plugin. What to do

[Lordtimothus666]

Whenever I want to watch a You Tube video or something else wich requires Adobe Flash Player, I get the message the Adobe Flash Player Plugin is missing and I have to install it. But the thing is I already installed it, many times.

So I searched the Internet for solutions and I discovered many others were also having the problem, but I didn't find any solution. I did try many things that were suggested on forums:
- I uninstalled it and re-installed it again

- I did a complete clean uninstall and re-installed it again

- I even re-installed all my browsers

...but nothing seems to work. I'm having this problem for about 2 weeks now and it's really getting on my nerves. No one on the web seems to know a solution. What am I supposed to do now?

Extra info:

- Adobe Flash Player version: 11

- OS: Windows Vista

- Browser: Opera, IE9

Yours sincerely!

Opera: check if the Shockwave Flash plugin is enabled.

IE9 does not use the plugin, but the ActiveX Control; do you have it installed?  If yes, check
