It’s really annoying me now because I am not able to install the Windows 8 OS even I have all the setup and things with me? I am just getting the error as “Windows cannot install required files. The files maybe corrupt or missing. Make sure all files are required for installation are available, and restart the installation. Error Code: 0x80070570”. What should I do now? Can you please give me the insight instructions to overcome this problem with my Windows 8 OS?
