Windows 10 showing error on installation

I was going to install Windows 10 version 1511 using the iso which i downloaded directly from the windows's website. But after the windows installer completed copying files and started the install it suddenly showed an error saying:

Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070570

I also tried reinstalling several times and deleted the folder which was created during copying the setup files but it didn't worked out. What to do now ?

Either the ISO you downloaded is corrupt or whatever media you put the ISO on is now corrupt. If you burned the ISO to a CD/DVD then you may just need to burn it again to a new disc. If the ISO itself is corrupt, you would need to download it again.
