It's really strange that you guys are having problems, I'm running natively (XP mode isn't even installed) in Win 7 Ultimate x64. Did those of you having problems try following the steps in my post on the previous page starting with an empty rebellion folder? (It's exactly what I did to get it working). If you copied everything from the CD smackw32.dll should be in the rebellion folder (66,560 bytes in size) so I don't know why it would say that is missing. Also make sure you're not running windowed and are running as an admin (when I run rebexe it automatically pops up a UAC dialog, I've not set anything special in the application's properties). The only things I can think of that may be different is that my files came from a Supremacy CD (UK release) and I have set my UAC down one notch, don't know if that has affected it.
