i'm trying to make a custom checkbox in my custom page (because is a one page installer), is needed only a checkbox without dialogs or anything, the installer that i'm trying to compile is very linear and simple.

i want to bind "FILE3.EXE" on a checkbox in this way: if checkbox is checked copy the file (FILE3.EXE) in DestDir, otherwise if checkbox is unchecked skip the file (FILE3.EXE) during installation.

This is the code that i use, obviously the checkbox code is missing because i'm not able to do that

[Files]
Source: FILE1.EXE; DestDir: {app};
Source: FILE2.EXE; DestDir: {app};
Source: FILE3.EXE; DestDir: {app}; //OPTIONAL

[Code]
procedure ExitProcess(uExitCode: UINT);
external '[email protected] stdcall';


var
MainPage : TWizardPage;
FolderToInstall : TEdit;
InstallLocation : String;


procedure CancelClick(Sender: TObject);
begin
if ExitSetupMsgBox then
begin
ExitProcess(0);
end;
end;


procedure BrowseClick(Sender : TObject);
var
Dir : String;

begin
Dir := FolderToInstall.Text;
if BrowseForFolder('Browse',Dir,false) then
FolderToInstall.Text := Dir;
WizardForm.DirEdit.Text := Dir;
end;


procedure InitializeWizard();

LabelFolder : TLabel;
