If you have downloaded Windows 8 Release Preview and tried to install it on your PC, but now getting an error message like this - “Your PC’s CPU isn’t Compatible with Windows 8″ during the installation process, then here I have a solution for you. Some users have also reported that they are getting this error even if their computers meets the minimum requirements which are needed to install Windows 8 Release Preview (RP). Although, I would recommend you to at first have a look at the minimum requirements of Windows 8 Release Preview below before trying to find an alternative solution to fix up this problem :
- Processor: 1 GHz or faster
- RAM: 1 GB for 32-bit or 2 GB for 64-bit
- Hard Disk Space: 16 GB for 32-bit or 20 GB for 64-bit
- Graphics Card: Microsoft DirectX 9 graphics device with WDDM driver
Now, if your computer meets all these requirements, then you may be wondering about why is this issue really occurring. Windows 8 Release Preview requires your PC’s processor to have all these features - PAE, NX, and SSE2. Nowadays, almost all the PCs comes up with all these features in their CPUs but Microsoft had recently stated that it is occurring because the NX feature is disabled in most of the cases. NX stands for “No Execute Bit” which might be disabled in your BIOS settings. So, just open up your BIOS settings and look out for an option to enable NX (No Execute Bit) or XD (Execute Disable Bit) and if you have found it, then just enable it once again. Now, try to install Windows 8 RP once again by booting the setup DVD during your computer’s start up, and the same problem shall not be appeared once again. And hence, the problem is solved and you are now ready to install Windows 8 Release Preview on your PC.
