Flash works fine in most cases but on some web sites I receive "The requested media player requires Macromedia Flash software. You have an old version of Macromedia Flash Player that cannot play the content we've created" and says to download and install the latest Flash player. The Adobe Flash Player site says Flash is working fine with the latest version installed. I went through the troubleshooting on the Adobe Flash player site plus others I found (uninstall/reinstall Flash, ActiveX off, Add-On enabled, etc). Did the "reset_fp11.bat.zip" Windows permission problem fix - no good. Tried all I could find - hopefully something stupid I haven't checked but tried my best! Checked the Guest account but same problem. Turned off antivirus - no good. But when I tried the 64-bit IE it plays with no problem. My wife has an essentially identical computer and it works fine in IE 32-bit version on these same sites. Windows 7 64 bit, Flash Version 11.3.300.270, Internet Explorer 9.
