I used the archive as I wrote and you're right when you say I have an invalid path of Universal Extractor in the path variable. I didn't remember its existence otherwise I would have deleted it. Ok, problem resolved. Although I think this is a bug. As I assume UE tries to find the extracting binaries in its path, can't find them but then uses PEID.exe in the current path (the one from which I launched it), is this right? Ok, it's a rare case ... anyway. As I said in my comments some week ago. A very nice application, thanks for it. Saluti
