Installation error: Setup cannot continue due to a corrupted installation file

I am installing Windows 7 (Custom installation initiated from Windows XP) but I get the following error message when the installation is on the "Installing updates" step of the installation:

"Setup cannot continue due to a corrupted installation file. Contact the vendor of your Windows installation disc or your system administrator for assistance."

Do you have any idea what the problem may be with the installation? Is there a way to see what file that may be corrupted?

I have tried to burn the DVD in low speed, but the error appears anyway. I have a MSI K8T Neo2-Fir mainboard and the Windows 7 upgrade advisor application says that my hardware is okay for upgrading.

What build of Windows 7? Are you sure your ISO matches the valid MD5 sum for that build?

It's the RTM build of Win7. How can I verify the MD5 sum of the ISO?

Check the download with a "MD5 checksum Checker".

If you have a different file the MD5 value will be different.

Okay, I understand. I will verify the MD5 value tonight (swedish time).

If we assume the DVD has the correct MD5 value, do you know if there is a way to see where the Win7 installation failed? Like a installation log file?

Unfortunately not. But I do have an idea how to circumvent the burning process, because I still think that might be having an effect. We'll see what happens with the MD5, though.

clifford_cooley: The MD5 checksum of the Win7 x86 ISO file I used did not match the MD5 that you provided in your post above, i.e. "28ECC57D83286BC15E7CF7A80CB940F3". I'm not familiar with how MD5 checksum comparisons work, but I guess this means the two ISO's are not the same.

However, what makes this a little strange; the ISO file I have is exactly the same size in bytes as your "2,501,894,144 bytes" and their filenames are equal.

Which code did you have? If the codes do not match then you could have a file that has been tampered with.

Try making a search on the internet for the code that your file generated and see if you find information on your file. If it is a Microsoft Leak or if it has been reported as a virus infected copy you should be able to find that as well. If you don't find anything, Then chances are you have a modified version and I would not use the copy.

If the MD5 does not match, then that is most likely the source of your issue.

The file names match because (obviously) you can name a file anything you want.

The sizes APPEAR to match because Windows displays file sizes in bytes, but each byte is 8 bits big. The number of bytes displayed is actually smaller than the number of bits that are really contained in the file. This means that a file can have subtle differences that won't be reflected in the file size.

You are correct in that the ISOs are not the same. You must redownload the ISO from a legitimate source, or verify that your... hmm... "Source" is authentic.
