Make MUI2 Welcome Page labels have transparent background

3

Edit: I found the solution see bottom text

I am attempting to make the MUI2 Welcome Pages' text have a transparent background.

I can get the text to have a transparent background for MUI1 but not for MUI2(the label windows keep their white background). Also would you suggest I just use MUI1 or is MUI2 much better to use?

Can you help me make the labels have a transparent background for the MUI2 Welcome Page?

Relevant Code(See below for all the code which you can compile to see the error):

!define MUI_PAGE_CUSTOMFUNCTION_SHOW WelcomePageShow
!insertmacro MUI_PAGE_WELCOME
Function WelcomePageShow
    # Why does the following code make the labels background transparent in MUI 
    # but NOT in MUI2???
    # What do I need to do to make it transparent in MUI2??

    ; Set transparent backgrounds.
    SetCtlColors $MUI_HWND 0xFFFFFF transparent
    !insertmacro SetTransparent $MUI_HWND 1201  # These aren't transparent in MUI2
    !insertmacro SetTransparent $MUI_HWND 1202  # These aren't transparent in MUI2

    # Make main white background a different colour
    GetDlgItem $R0 ${MUI_HWND} 1044
    SetCtlColors $R0 0x444444 0xff0000         # The background colour doesn't change in MUI2
    # Make smaller white background a different colour
    GetDlgItem $R0 ${MUI_HWND} 1018
    SetCtlColors $R0 0x444444 0x00ff00         # The background colour doesn't change in MUI2 
    Call RefreshParentControls
FunctionEnd

All Code:

!include MUI2.nsh   # change this to !include MUI.nsh to see how the code works successfully for MUI1
!include WinMessages.nsh
!include "LogicLib.nsh"

; Local bitmap path.
