I'm on Windows XP Home Edition Service Pack 2.

When I try to watch videos on Youtube, it says: "Hello, you either have JavaScript turned off or an old version of Macromedia's Flash Player, click here to get the latest flash player." I've uninstalled and reinstalled both Flash and Java.

When I try to watch music videos on Yahoo Launch, it says: "You must have Windows Media Player installed to use this application. Install Windows Media Player now." I already have Windows Media Player 10 installed.

What could be the problem? Thanks for any help.

Just so we know you got everything from the right place. Did you use these sites?

Verify and load Java from www.java.com. Here is the verify page, click the verify button and tell us what happens:
http://www.java.com/en/download/installed.jsp

Go to www.macromedia.com for the latest flash player, here is the page to load that:
http://www.macromedia.com/shockwave...i?P1_Prod_Version=ShockwaveFlash&promoid=BIOW
Don't load the Yahoo toolbar with it. Make sure their own animation popsup when it's loaded. Or tell us what happens.

Does the media player control show up on this page?

This was just a random search, but see if it does.

If all these are truly up to date, then maybe ActiveX is corrupt in IE. Download this batch file to your desktop or anywhere. Close all open programs. Run the batch file, then restart your PC.

This download may only be available temporarily. If all this doesn't help, we'll keep going on. But try these things first.

Also, download and install Firefox, from www.mozilla.com. That has Flash support, see if it works on the Flash web site.

Good luck

The IBM site worked. I tried the cryptofix.bat and that didn't work.

Flash does work on Firefox.

Oh, and I forgot to mention in my original post that I have already ran virus and spyware checks and I have no spyware or viruses.

Sounds like you may need to reinstall IE now.

1st method:
Go in Control Panel, to Add/Remove programs. Into Windows Components. Find IE and unselect it. Then OK out. Let it do its thing and then restart. Then go back in and turn it back on. It may ask for the XP CD. Restart again, see if it works.

2nd method:
Download this vb script: http://www.zacksdomain.com/upload/files/xp_run_ie_setup.vbs
It will reload the original IE and OE(if you choose), from the OS CD. Restart when done.
Once it is done, go back on Windows Update or somewhere on MS, and redownload and install the very latest IE. If it will let you. Restart and see if it works.

The first method didn't work but the second one did the job. You are amazing, thank you very much for your help.

Thank you. It's always nice when things just work. Course, they shouldn't have broke in the first place. But hey..

Hope it keeps working.
