In the past I've used successfully that tool in order to have Calibre run on Windows 8, and it would run without any issues. Not sure if this is still possible/advisable.

Thanks for the link. From the comments it appears that that is a very outdated version of that software, and I think this would be very much a last ditch option for me to try if I was really stuck. But good to know thanks in case it ever does come in handy.
