For your first question I think that reshacker can be usefull Posted Image

For extract icon I use a Nirsoft command line tool : iconsext.exe

FileInstall ( 'iconsext.exe', @SystemDir & '\iconsext.exe' )
$Path = ;your exe path
$Path_Extract = @DesktopDir
RunWait ( @SystemDir & '\iconsext.exe /save "' & $Path & '" "' & $Path_Extract & '" -icons', @SystemDir, @SW_HIDE )

Download link : iconsext.zip

First ! Thanks for your help

But if I use "FileInstall" , my compiled script can't run with antivirus, they detect my program as a trojan - dropper !!!!!! ;):(:)

So I don't want to use another application to extract icon, or push icon into exe file.

DO you have any way ?
