Q: The application or DLL \Sources\SPWIZENG.DLL is not a valid Windows image, The file 'autorun.dll' could not be loaded or is corrupt.[0xC1] This thread is locked from future replies

Trying to load Win 7 from an iso, when starting immediately get "The application or DLL \Sources\SPWIZENG.DLL is not a valid Windows image. Please check this against your installation diskette." Hit 'ok' then get "The file 'autorun.dll' could not be loaded or is corrupt. Setup cannot continue. Error code is [0xC1]"

I rec'd my iso from my place of higher education (student software), and once I started to run into all of these problems asked a friend to create an iso off of his disk prior to him loading straight off of his OTC DVD and we can duplicate the error.

I have used several burn programs nero/magic iso/sonic to try to burn the image but all produce the same results. Searched the forum and nothing like this had been posted yet, and although I have seen this error throughout Google no one had a good answer what it was or how to fix it.

Currently run XP Pro 64, and the iso is Win 7 Pro 64



Hi IT_Crash,

The most likely and possible cause of this error is bad media or corrupted ISO. I’d suggest you to re-download the ISO and then burn the same with the lowest burning speed.
