Delphi 10 : showing a DLL's form when compiling with runtime packages

Question

Sorry if this question has been asked in the past, but i'm confused!

I have an app and a DLL, both in Delphi. The Dll has a form that i want to show(no modal) inside a Groupbox. In the main app i have enabled runtime packages. In the DLL if i disable them, then works ok with the code bellow.

in DLL :

procedure showInfo(app : Thandle; GB : TGroupBox); stdcall;
begin
   // application.Handle := app; // are the same
    FormSysInfo := TFormSysInfo.CreateParented(GB.handle);
    FormSysInfo.show;
end;

procedure destroyInfo; stdcall;
begin
    FormSysInfo.destroy;
end;

exports showInfo    index 1,
        destroyInfo index 2; 

in main app :

procedure loadSysInfo;
var showInfo : procedure(app : Thandle; GB : TGroupBox); stdcall;
begin
    sysInfo := LoadLibrary('SysInfo.dll');
    if sysInfo <> 0 then begin
        @showInfo := GetProcAddress(sysInfo, 'showInfo');
        @destroyInfo := GetProcAddress(sysInfo, 'destroyInfo');
        if @showInfo <> NIL then      showInfo(application.handle,mainForm.GroupBox8);
    end;
end;

but didn't show if i enable runtime packages for the DLL (I want to reduce the size). How can i manage this, please ? thanks in advance
