Adding text to the completed dialog of an NSIS installer

Question

I'm trying to add text or add an extra dialog at the end of an NSIS installer. So, to clarify, when the install has completed successfully I want to show some information.

I've seen various examples that touch on it but none seem to actually present a solution.

Does anyone have any info that can help?

You are already using the MUI so you can just customize the finish page text to fit your needs:

!include MUI2.nsh
!insertmacro MUI_PAGE_INSTFILES
!define MUI_FINISHPAGE_TITLE "Custom title"
!define MUI_FINISHPAGE_TITLE_3LINES
!define MUI_FINISHPAGE_TEXT "Custom text blah blah blah$\r$\nblah blah blah$\r$\nblah blah blah$\r$\nblah blah blah$\r$\nblah blah blah$\r$\n"
!insertmacro MUI_PAGE_FINISH
!insertmacro MUI_LANGUAGE English

And if that is unacceptable for whatever reason, you can create a totally custom page:

!include MUI2.nsh
!insertmacro MUI_PAGE_INSTFILES
AutoCloseWindow True ; Automatically move on from the InstFiles page
Page Custom MyFinishPageCreate
!insertmacro MUI_LANGUAGE English

!include nsDialogs.nsh

Function MyFinishPageCreate
!ifdef MUI_SYSVERSION
!insertmacro MUI_HEADER_TEXT "Title" "Sub-title"
!endif
nsDialogs::Create 1018
Pop $0
${NSD_CreateLabel} 0 0 100% 12u "Blah blah blah"
Pop $0
${NSD_CreateLabel} 0 30u 100% -30u "More blah blah blah"
Pop $0
nsDialogs::Show
FunctionEnd

If you want to display text directly on the InstFiles page you have to create a label control manually:

!include LogicLib.nsh
!include nsDialogs.nsh
!include WinMessages.nsh

Page InstFiles "" InstFilesShow

Var MyText
Function InstFilesShow
; Cannot use CreateWindowEx in a Section, must do it in the show callback
FindWindow $1 "#32770" "" $HWNDPARENT # Finds the inner dialog
System::Call 'USER32::CreateWindowEx(i${__NSD_Label_EXSTYLE},t "${__NSD_Label_CLASS}",t "Text goes here",i${__NSD_Label_STYLE},i10,i100,i300,i200,p$1,p0,p0,p0)p.s'
Pop $MyText
ShowWindow $MyText 0
SendMessage $1 ${WM_GETFONT} 0 0 $2
SendMessage $MyText ${WM_SETFONT} $2 1
FunctionEnd

Section
${IfNot} ${Abort}
    ShowWindow $MyText 1
${EndIf}
SectionEnd
