Problem with isobuster

I am trying to extract some MDF and MDS files using isobuster. It does it and brings the list of files up… Including AutoRun.exe which is the one i desperately need. However, it has a red cross beside it and when i try to extract the .exe file, it says

Sector 10224 could not be read.
Error 05/63/00

I managed to get a different autorun thing but when i try to run it, it says “This is not a valid win32 application.”

Can anyone help me solve any of these problems? Thanks.
