error code:0x80070570

Question

first of all sorry for my bad English..

I have downloaded windows8 developerPreview-32bit-English (2.8 GB) successfully..
made a bootable USB and tried to install (fresh install).
when it comes to expanding files at 57% it gave error code:0x80070570 and tried again.
same error..
tried to install on VMWare, Virtual Box directly with ISO..
same error.
on the other system with different configuration..
and again same error..

so, i searched on google. only the solution there may be problem with ISO is to re-download ISO..
but my net speed is very very low (download sppeds upto 12 kbps).
i downloaded it 2.8 with great difficulties.. (took 5 days to download.)

i can't download it again..

is there any alternate solution like rebuilding the ISO with working files.
is it possible to know which files of ISO are corrupted and replace them with working files..

pls help...

Answer 1

you can check the checksum [SHA1], for the ISO file

Sha 1 hash - 4E0698BBABE01ED27582C9FC16AD21C4422913CC

you can find a free tool for check the sum here:

The SHA-1 doesn't match, it was corrupted while downloading. You will need to redownload the WDP:

If you're using a browser to download it, try using a download manager instead. They can be more reliable with large files, and most allow pausing and resuming if you have a slow connection.

Free Download Manager is a popular one:
