Adobe Flash Player 10

[has]

I'm trying to download Adobe Flash Reader Player 10, as I wish to view video clips on youtube, because I keep getting the following message –
Hello, either you have JavaScript turned off or an old version of Adobe's Flash Player. Get the latest Flash player.

I go through the exact process stated, click install & then after the green bars have finished, an error message appears saying…Error - Failed to register…& I haven't got a clue why.

I've uninstalled any existing Adobe stuff from My Computer., as I’ve downloaded & run this application.

Any advice would be greatly appreciated, but must be in simple, simple terms please.

The PC is running Windows XP.

I desperately need any help, the simpler the better.

Thanks.

Do you really need to put this in the Technology AND the Computers AND the Internet sections?

Any one of the three would have done.

And I now notice you have put it in !"How it works" as well.

I hope you dont get any answers.
