“只读”或“禁用灰色任务”复选框？

Question

I would like to disable and set to gray color, or set to readonly, some task checkboxes, the checkboxes that are checked in this image:

I'm not looking for other kind of approach, I want to make visible those Tasks but make their checkboxes uncheckeable, that's all, this way the user can see what is going to be installed and what is restricted by default.

My Install script looks like this:

Is this possibly to accomplish?

I didn't found any Task flag that helps me to do this, in the other hand, I've seen other questions in StackOverflow but are related to readonly checkboxes and it uses pascal-script code, I'm not a pascal script code and I'm not sure whether that is what I need to do because I'm not creating and instancing manually the checkboxes in the Form, I mean that I don't have any control on those checkboxes+labels, I'm just adding tasks in the Task section.

UPDATE

I'm using the pascal-script code below to disable the desired items, but when I run my installer I get this error, it says that the index is out of bounds, why?, I'm using the proper chekbox indexes and I've verified the indexes seeying the resulting task page... I think that the problem is the wpSelectTasks, it is an integrated constant?, anyways I've tried to specify a constant with the pagenumber of the tasks page and I still get the same error, and the error occurs when I change the selected page using the 'Next' button (not 'Back'):

// Disable Tasks

procedure CurPageChanged(CurPageID: Integer);
begin

  // if we have entered the tasks selection page, disable the specified Tasks.
  if CurPageID = wpSelectTasks then
    WizardForm.TasksList.ItemEnabled[11] := False;
    WizardForm.TasksList.ItemEnabled[12] := False;
    WizardForm.TasksList.ItemEnabled[13] := False;
    WizardForm.TasksList.ItemEnabled[14] := False;
    WizardForm.TasksList.ItemEnabled[15] := False;
    WizardForm.TasksList.ItemEnabled[30] := False;
    WizardForm.TasksList.ItemEnabled[32] := False;
    WizardForm.TasksList.ItemEnabled[33] := False;

end;

// Disable Tasks - END

I have more code for UI customizations and I don't know if some thing is in conflict with the other procedure, the entire [Code] section is this:

[Code]





// Disable Tasks

procedure CurPageChanged(CurPageID: Integer);
begin

  // if we have entered the tasks selection page, disable the specified Tasks.
  if CurPageID = wpSelectTasks then
    WizardForm.TasksList.ItemEnabled[11] := False;
    WizardForm.TasksList.ItemEnabled[12] := False;
    WizardForm.TasksList.ItemEnabled[13] := False;
    WizardForm.TasksList.ItemEnabled[14] := False;
    WizardForm.TasksList.ItemEnabled[15] := False;
    WizardForm.TasksList.ItemEnabled[30] := False;
    WizardForm.TasksList.ItemEnabled[32] := False;
    WizardForm.TasksList.ItemEnabled[33] := False;

end;

// Disable Tasks - END
