Flash Player 11_8_800_94 on Terminal Server

Hi

I have a problem with the newest Version of Flash Player on a Windows Server 2008 R2 Terminal Server.

I have installed Flash as Administrator with "change user /install". Everything works fine as Administrator but as a normal User with User Rights I can not see Flash in the Plugins.

I found thousands of articels with older Versions but nothing helped me.

Windows Server 2008 R2  64 bit

IE 9

Flash Player 11_8_800_94

Has someone a Idea?

Thanks

Werrner
