Windows 7 RC Build 7100 Installation Error 0x80070570 at "Expanding Files"

[Radhesh Bhoot]

I'm here hoping somebody else has recieved this error message and knows how to fix it.

I'm experiencing a strange problem when installing Windows 7 RC Build 7100. At the file expansion stage, error code 0x80070570 appears and my installation fails.

Exact message:
"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"

Does anybody have any idea how to get it installed?????

It may be because u are trying to run the setup from ur hard disk. Burn the ISO image on the DVD and then try it.

I dont think the source of install is your problem. I had faced it during beta installation(dont remember the error code).

The ISO file was corrupt. Ran a MD5 checksum and compared it with other users result posted on the net.

I had to download it again and make sure that the download was not interrupted due power failures.

Go get a torrent of the RC and point it to the ISO via your torrent app. It should repair your ISO and then re-burn and try installing.

Here is the MD5 checksum for the iso I downloaded: 8867C13330F56A93944BCD46DCD73590

(It is the 32 bit one - 7100.0.090421-1700_x86fre_client_en-us_retail_ultimate-grc1culfrer_en_dvd.iso)

Thanks Unni n techno Funky...

It did solve the problem......It was so Simple yet so brillant solution.....
The Problem was that some 6MB Data was corrupted or being written in the file as i have downloaded it from Microsoft's through Flashget....but this torrent replaced it and it is now working......

Thnks once again dude.....

Its not the prob of your build.Its the prob of your optical drive.Some drives read only perfect disks
