Can't install Adobe Flash player

Hi,

I tried to install AF several times but it gets to the same point each time and stops, saying I need to close Internet Explorer. As far as I can tell it is not open. Looked through the help files but did not find this issue. Followed directions and have Scripting set right as well as Activex settings. Any help would be great.

Thanks,
