Instillation of Adobe Flash Player

Well, I have done this instillation a bunch of times now.  It tells me it is installed.  When I check it with an uninstall program, it is there.  BUT, when I try to use it for Hulu, it keeps telling me that it isn't installed and wants to do an install (which I had done several times.)  I am running Windows 7 Home Premium on an AMD dual core system.  I have tried every way I can think of to get it to work, and I have come up blank.  Back when Adobe was having security problems last month, I uninstalled all the Adobe free products.  Now, I have done the install of the Flash Player a bunch of times (including using the Adobe uninstaller, once between times.)  I am using Firefox, but I also attempted to do it in Internet Explorer 11 as well.  Nothing has worked.  No Adobe Flash Player shows in the ad ins, either.  STUCK!
