Flash player only works with Chrome not Explorer What's UP?

[Explorer-Problem]

I have installed both the default version of Flash Player and the Version for Windows Vista and Internet explorer, both with and without installing Google Chrome. When I goto a site I.E. Youtube with Windows explorer I get a message that I need to install Flash player. If I use Chrome it works fine. Before each new instalation I uninstall the previous Install and reboot the system. For some reason Flash player seems to only work with Chrome now. I just started having this problem Wednesday. I have made all the sugested modafications to Windows Explorer. Any Idea what is going on?

Chrome has its own Flash Player built in by Google. It functions independently of the ActiveX plug-in for IE.

See: http://forums.adobe.com/thread/885448  and  http://forums.adobe.com/thread/867968  to be sure it's properly enabled and the ActiveX filtering isn't blocking Flash.
