Hi! If there's a thing that prevents me from using 7zip only, it's lack of .ace support... since i don't want any commercial software, i've found this little Xace extractor (from Winace site). But the installer is rather uncommon: it starts with a welcome page and, after the first "Next", it goes on with the first installation window, of which i attach a screenshot. It's not InstallShield, nor MSI, nor NSIS, nor WISE, nor INNO. I've tried several common switches but there's no reaction whatsoever. Any clue? Thanks in advance
