Hi Philippe May i asked what the advantage is against a 7z compressed msi file? If you remove code from code it gets smaller because you can still apply compression afterwards and it gets even more smaller. These exe compactors do not reduce the used RAM memory when loaded actually afaik more memory is used because OS cannot page from dll file. And why do you send a link to a commercial packer instead of UPX?
