I have duplicated InitializeSetup in INNO SETUP how can i solve it? - installation

Question

Hello i am trying to make an installer using INNO SETUP, when i started to use ISSkin Code Inno setup send me an error mesage DUPLICATE IDENTIFIER 'INITIALIZESETUP' I would like to know what i have to change to my code to make it work.
I was reading at internet and i found a program called IS Script Joiner, i used it but it doesnt work.
Here is my Inno Code:
; Script generated by the Inno Setup Script Wizard.
; SEE THE DOCUMENTATION FOR DETAILS ON CREATING INNO SETUP SCRIPT FILES!
#define MyAppName "Myprogram"
#define MyAppVersion "2.8"
#define MyAppPublisher "Myprogram"
#define MyAppURL "http://www.example.com/"
#define MyAppExeName "program.exe"
#define ISSI_WizardSmallBitmapImage "wpBanner.bmp"
#define ISSI_WizardSmallBitmapImage_x 495
#define ISSI_WizardSmallBitmapImage_Align
#define ISSI_IncludePath "C:\ISSI"
#include ISSI_IncludePath+"\_issi.isi"

Thank You very Much for Your Help

Relocate the two calls to the ISSkin DLL from where they are now (above the second InitializeSetup) to just above the first InitializeSetup declaration.
// Importing LoadSkin API from ISSkin.DLL
procedure LoadSkin(lpszPath: String; lpszIniFileName: String);
external 'LoadSkin#files:isskin.dll stdcall';
// Importing UnloadSkin API from ISSkin.DLL
procedure UnloadSkin();
external 'UnloadSkin#files:isskin.dll stdcall';
Change the first InitializeSetup code to include the calls to extract and load the skin (from the second InitializeSetup).
function InitializeSetup: Boolean;
var
V: Integer;
iResultCode: Integer;
sUnInstallString: string;
begin
// These two lines moved from second InitializeSetup declaration before it
// was removed.
ExtractTemporaryFile('iTunesB.msstyles');
LoadSkin(ExpandConstant('{tmp}\iTunesB.msstyles'), '');
Result := True; // in case when no previous version is found
if RegValueExists(HKEY_LOCAL_MACHINE,'Software\Microsoft\Windows\CurrentVersion\Uninstall\ {2A8CE1DB-2FDB-4CAA-8A2C-0FE2DB8A500D}_is1', 'UninstallString') then //Your App GUID/ID
begin
V := MsgBox(ExpandConstant('Myprogram is Already installed, Do you want to continue?'), mbInformation, MB_YESNO); //Custom Message if App installed
if V = IDYES then
begin
sUnInstallString := GetUninstallString();
sUnInstallString := RemoveQuotes(sUnInstallString);
Exec(ExpandConstant(sUnInstallString), '', '', SW_SHOW, ewWaitUntilTerminated, iResultCode);
Result := True; //if you want to proceed after uninstall
//Exit; //if you want to quit after uninstall
end
else
Result := False; //when older version present and not uninstalled
end;
end;
Remove the second InitializeSetup code entirely.
