I tried updating the firmware of my Harman/Kardon AVR255 with Windows 7 Ultimate x64, but it always failed at the video subsystem part with the message: “AVR didn’t respond properly. Video subsystem upgrade failed.”
Then I tried using Windows XP Mode for Windows 7 and it worked! 😀
Hi I have the same problem.
How did you use “Windows XP Mode for Windows 7”?
Did you just changed the properties of the .exe file to “compability, run this program in Windows XP mode (service pack 2)”?
Thanx!

Hi Kim,
No I really mean XP mode as described here: http://windows.microsoft.com/en-US/windows7/install-and-use-windows-xp-mode-in-windows-7
