CPU not supported by Windows 8 RP?!

[IvyDeneb]

I just finished downloading Windows 8 RP and when I try to install it (upgrade method) It says Windows 8 doesn't support my CPU.

My CPU: Intel Pentium Dual Core E2200 @ 2.2 Ghz

Thing is I was able to install Windows 8 DP/Beta on this Machine fine. I don't know what is wrong with this. I just wanted to test Windows 8 RP on my system...
