Problem in installing Windows 7 on 32 bits

Hello everybody, I would like to know because I could not install windows 7 beta I downloaded direct from Microsoft 2 times what I record to a dvd using Ashampoo Burning Studio 7 I've also recorded with nero 7 and 9.

My problem is that when extracting the files are left in the (7%) and leaves the message with the following error code: 0x80070570

Windows can not require INSTALL files. The missing file may be corrupt. Make sure all file required for installation are available, and restart the installation.
Error code: 0x80070570

Ya, I tried a thousand ways:

leaving only a hard drive for my pc is 2, the two are connected, nothing works and nothing ever stays the same error (Error: 0x80070570)

I can help to analyze what is my problem, DVD is not damaged because I have already spent 8 DVD is the same and always recorded at various speeds from 2x to 4x different programs recorders images.

Hi,

See what Microsoft says about it:

I have several machines. (64 bit)One I have previously used for installing 7 is a 3.2 dual core with 4gbs ram. I am also confused by reports of installations only taking, in some cases, as little as 15 minutes. I consider the install right up to the desktop, including setting up the Internet/Lan. I have never achieved better than 30 minutes. If you include the updates, which come almost immediately after the completion, you can add on at least another 5 minutes.

But, aside from that, you have most certainly got something wrong with your setup. Even with your slower machine, the time is ridiculous!
It would be odd if a corrupted disk would cause such a strange problem. If it was that corrupted, I would have doubted it would complete the install.

Ok, thank you thank you, finally can realize that the error was due to the information you gave me to see:

The error occurred because the installer so I downloaded using Windows Vista and it seems that with this operating system so that the image is saved correctly installer must make a series of step.

What I did was download it from Windows XP and you're done with that I was super, in fact I am typing this message from Windows 7, which certainly did not see anything new, just little things I notice here and there that have been brought together in a and new applications that do not are left to install, well after all it is a beta but good ....
