Answer

well thanks Davion, i found a way to do what i need and i'll post the little code for this purpose.

this goes in the section where u select the files, or it can be too on the section where u run other programs, in case u want to install first the prog u are going to read the value of, for the installer. It reads the Reg Value where the path of the program is installed, and assign that value to $0, after that i say to it that the output dir where i'm gonna copy those files is $0, and where the files to copy are.


ReadRegStr $0 HKLM "SOFTWARE\Firebird Project\Firebird Server\Instances" DefaultInstance
SetOutPath "$0"
File "C:\ib6\RunImageLw2\firebirdsecurity\*"

hope it helps someone with the same prob i had. sorry for my bad english 😁
