Refreshing MUI InstallOptions page after NOTIFY control used
Heres my situation: I have a custom InstallOptions page with NOTIFY controls, which execute correctly when clicked or manipulated in the compiled installer, but the page doesnt refresh! I have to press "back" then "next" to see the changes that were made.
Heres my custom page code:

Function ShowFileOptions
    ${If} $ShowLiscense = 0
        !insertmacro MUI_INSTALLOPTIONS_WRITE "FileOptions.ini" "Settings" "NextButtonText" "Finish"
    ${Else}
        !insertmacro MUI_INSTALLOPTIONS_WRITE "FileOptions.ini" "Settings" "NextButtonText" "Continue >"
    ${EndIf}
    
    !insertmacro MUI_HEADER_TEXT "$(TEXT_IO_TITLE)" "$(TEXT_IO_SUBTITLE)"   
    !insertmacro MUI_INSTALLOPTIONS_INITDIALOG "FileOptions.ini"
    Pop $HWND
    !insertmacro MUI_INSTALLOPTIONS_SHOW
FunctionEnd

Function LeaveFileOptions
    !insertmacro MUI_INSTALLOPTIONS_READ $R0 "FileOptions.ini" "Settings" "State"
    StrCmp $R0 0 Done
    StrCmp $R0 7 AddBtn
    StrCmp $R0 10 EditBtn
    Abort
    
    AddBtn:
        !insertmacro MUI_INSTALLOPTIONS_READ $R1 "FileOptions.ini" "Field 3" "State"
        !insertmacro SMIS_APPEND "$R1" "FileOptions.ini" "Field 5"
        Abort
    
    EditBtn:
        !insertmacro MUI_INSTALLOPTIONS_WRITE "FileOptions.ini" "Field 6" "Flags" "DISABLED"
        Abort
    
    Done:
FunctionEnd

You can't do it that way because the InstallOptions page is in memory and no longer read from the INI file.
You must manipulate the dialog in memory with GetDlgItem and SendMessage etc

You already have the code ready to use $HWND in your leave function.

Is there any more extensive documentation of the SendMessage and related commands? the NSIS help files that come with dont list any of the message numbers and barely glaze over what the function does.

Try this example InstallOptions script:
