Dear Jim Booth :

Thanks in advance for your reply.

I already tryed your sugestion, but it didnt work !
My problem gets better ... somethimes the compression ratio (in zip file) is, lets say 0.2% , then i redo the EXE (without coding a line) and i get 10.8%, and the process of compressing and building goes on.
Usualy i get 0.2%, but sometimes i get diferent values!
(in setup too, it even gets the EXE bigger when is compressed !)

Once again thank you for your help!
