ISSkin fuction InitializeSetup help

Hi, i found my problem using ISSkin + ISSI, i need to change the name fuctions of :

function InitializeSetup(): Boolean;

and

procedure DeinitializeSetup();

to a new name and get it working because ISSI already taked InitializeSetup name, how i can change the names of these fuctions and
get the ISSkin working?

I tried to change to :

#define ISSkinInitialize Setup
#define ISSkinDeInitialize Setup

and

[code]
// 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';

// Importing ShowWindow Windows API from User32.DLL
function ShowWindow(hWnd: Integer; uType: Integer): Integer;
external 'ShowWindow@user32.dll stdcall';

function ISSkinInitializeSetup(): Boolean;
begin
    ExtractTemporaryFile('lightgrey.cjstyles');
    LoadSkin(ExpandConstant('{tmp}\lightgrey.cjstyles'), '');
    Result := True;
end;

procedure ISSkinDeinitializeSetup();
begin
    // Hide Window before unloading skin so user does not get
    // a glimse of an unskinned window before it is closed.
    ShowWindow(StrToInt(ExpandConstant('{wizardhwnd}')), 0);
    UnloadSkin();
end;

But is not working, someone can helpme to change name of the process of InitializeSetup to "newname" and get it working?

yes i try to moddify ISSI, but didnt work 100%, i losse some features like SplashScreen.

The question if there are a way to change InitializeSetup for example InitializeSetup2 and get it
working. can you help me please!!! can you?

the problem??? well i modify the sources of ISSI exactly like you said, and offcourse works and can uses ISSI + ISSKIN,
but lost some features on ISSI like SPLASH SCREENS etc..
