Can't open Settlers IV cracks! Please help!

[znake]

I don't know what I'm doing wrong here, but everytime I try to open these Settlers IV fixed exe's or no-cd's I get this weird error message saying something like "unsupported method: 2, skipping s4_main.exe" or something. I've tried different files from different sites, but it's always the same thing. For unpacking I've tried ArjFolders and PowerArchiver but no success. Please guys, tell me how to open these files. They can't all be corrupted!

Thanks in advance.
