How do you read the ini-fail contents during installation?

[guilherme]

It shall be necessary to read the values from one ini-fail at the time of installation and to record them in another ini-fill. The function of reading the line from the ini-fail somehow returns the default value to it, not the file. File's lying there, there's a point in it.

This is the example of the crypt, which reproduces the problem:

[Setup]
AppName=MyApp
AppVersion=1
DefaultDirName=D:\Projects\Test\
DisableDirPage=yes
Uninstallable=no
[INI]

Filename: "{app}\INIFile2.ini"; Section: "Section"; Key: "Key1"; String: "{code:GetIniFileValue|'Key1'}"

Filename: "{app}\INIFile2.ini"; Section: "Section"; Key: "Key2"; String: "{code:GetIniFileValue|'Key2'}"
[Code]

function GetIniFileValue(const Key: String): String;

begin

Result := GetIniString('Section', Key, 'DefaultValue', 'D:\Projects\Test\INIFile1.ini');

MsgBox(Result, mbInformation, MB_OK); // сообщение выводит результат функции GetIniString

end;

Contained file INIFile1.ini:

[Section]

Key1=Value1

Key2=Value2

Once the installation has been completed, the file will be delivered INIFile2.ini of the following contents:

[Section]

Key1=DefaultValue

Key2=DefaultValue

How do I get the first file?

The error was in the transfer of parameters to the function, the parameters were to be stated without single quotes:

[INI]
Filename: "{app}\INIFile2.ini"; Section: "Section"; Key: "Key1"; String: "{code:GetIniFileValue|Key1}"
Filename: "{app}\INIFile2.ini"; Section: "Section"; Key: "Key2"; String: "{code:GetIniFileValue|Key2}"

UPD: I found another excellent version of reading ini-fail without adding the code.

Filename: "{app}\INIFile2.ini"; Section: "Section"; Key: "Key1"; String: "{ini:{app}\INIFile1.ini,Section,Key1}"
