Get the version of a exe or dll from inno setup

How I can get the version number from a exe file or a dll using Inno, I tried the Get开发者_运维百科FileVersion function but only is available in the Inno Preprocessor (and I need use this function in the [Code] section of my script) . Also I tried the GetFileVersionInfo function but is not recognized by Inno.

Try

function GetVersionNumbers(const Filename: String; var VersionMS, VersionLS: Cardinal): Boolean;

and/or

function GetVersionNumbersString(const Filename: String; var Version: String): Boolean;
