Hello,
I have two PCs. One is running 32 bit Win7 SP1, the other 64 bit Win 7 SP1. Both have IE9 32 bit and the latest version of Flash 32 bit, 10.3.183.7. This page http://www.iorr.org/talk/read.php?1,999739 and others at iorr.org have embedded YouTube Flash videos. On the 32 bit machine, they play fine on both Admin and Standard accounts. On the 64 bit machine, the embedded videos are only visible on the Admin account. Standard accounts show an empty box with a broken icon symbol where the video should be. (Note: not trying to use IE9 64 bit.)
I've spent a couple hours uninstalling and reinstalling Flash trying to see the videos on a Standard account on the 64 bit PC. Nothing works. Any suggestions? Note that normal Flash videos work fine on the 64 bit PC Standard accounts. Only embedded videos fail.
During this exercise, I noticed that the 32 bit PC has the Flash Player Control Panel under Control Panel->System and Security. The 64 bit PC does not have it there, but I can manually bring it up from a CPL file in the SysWOW64 folder. Not sure if that's part of the problem or a different problem.
Thanks for your time.
