Windows 7 64 bit includes Internet Explorer 8 32 bit so you can view Flash content on the web.
Please note, if you using a 64 bit version of Windows 7, you need to use the 32 bit version of Internet Explorer 8 that is included with the operating system. Adobe Flash Player does not support 64 bit version of Internet Explorer in Windows 7 at this time.
Click Start > All Programs > Click Internet Explorer (the one that is not listed as 64 bit)
Adobe Flash Player is not supported for playback in a 64-bit browser
