Hi I've got OEM version of W7 Pro 64 bit. I've had it about 2 months and everything is working fine except IE8 64 bit. I normally use Firefox so haven't been to concerned. I'm now trying to figure out why my IE8 64 bit dosn't work. The IE8 32 bit works fine. The error I get when I start IE8 64 is The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher. I've downloaded IE8-WindowsVista-x64-ENU and tried installing that but get the error Internet Explorer 8 is not supported on this operating system. I've checked in control panel system and it reports my o/s IS 64 bit. Any ideas.
