I just realized my error seems a little different than others.
My problem is not when using Daemon Tools. Once the autorun is selected for the first disk (after being mounted), I get this error.

Sorry thats hard to read "G:\ The version of this file is not compatible with the version of windows you're running. Check your computer's system information to see whether you need an x86(32-bit) or x64(64-bit) version of the program, and then contact the software publisher."
I am running Vista home premium, 64 bit, Intel core duo.
Sorry if this is posted elsewhere, I have sincerely been searching.
Edit 2: Upon some reading at other websites, I think it may be a bad download? Trying the one linked in the setupguide.
Edit 3: Yup, it was the download.
