Error 0x000000C4 when installing 8.1 from DVD fresh install
I just bought the full version of 8.1 to install on a new hard drive. The CPU is an Intel Core 2 duo E8400. When I try to use the 64 bit install DVD it shows the windows logo with no loading indicators. It will show that for a minute or two then briefly
flash the error code of 0x000000C4 and then reboot the computer. Everything is set to 64 bit in the BIOS but still give that error. All instruction sets required appear to be supported by the CPU. 32 bit version will progress to the first menu prompt but I
haven't gone any further as I want to install the 64 bit version instead of the 32 bit version. Hard drive is fresh out of the box and installed fine. Do I maybe have a bad disk or something? Thanks

I was also looking for this answer and after research found that error could be because Microsoft made a subtle change to the system requirements from Windows 8 64-bit to Windows 8.1 64-bit, which is the system needs to support the CMPXCHG16B feature in
the CPU. Your CPU supports that feature.
Further research has shown that in reality not only does the CPU need to support this feature but the motherboard does also. In your case, you may need to flash the BIOS on your motherboard.
fooling around with a Dell Dimension 4700, changed the CPU to Pentium 541 - which specifically includes 64bit capability. 4G of RAM. all peripherals disconnected except usb keyboard and mouse. W8.1 Full Retail DVD endlessly cycles w the mentioned error
code (I had to film the screen with my iphone and play it back to "freeze" it and read the code). W8.1 32-bit installs wo problem. I ran DBAN to wipe hard drive and then attempted 64 install - same results. any suggestions? I know it's an old machine,
but it ran XP flawlessly, it was free when a friend bought a new machine, I'm a pack-rat, and this is actually more fun to try to figure out than playing Candy Crush. thx, kyle
