Customize uninstaller Confirm page using MUI2 and nsDialogs
  Hi everyone!
I'm stuck trying to add a checkbox on Uninstaller Confirm page. I'm using MUI2 and nsDialogs the following way:

define name customconfirm

>!include "MUI2.nsh"


>OutFile      "${name}.exe"

>Name         "${name}"

>InstallDir   "$TEMPDIR"


>var unCheckbox


>Function un.MyConfirmShow

    MessageBox MB_OK "Showing confirm page"

   ${NSD_CreateCheckbox} 50% 50% 100% 10u "&My checkbox"

    Pop $unCheckbox

    SetCtlColors $unCheckbox "" "ffffff"

>FunctionEnd


>!insertmacro MUI_PAGE_DIRECTORY

>!insertmacro MUI_PAGE_INSTFILES


>!define MUI_PAGE_CUSTOMFUNCTION_SHOW un.MyConfirmShow

>!insertmacro MUI_UNPAGE_CONFIRM

>!insertmacro MUI_UNPAGE_INSTFILES


>!insertmacro MUI_LANGUAGE English


Section

    WriteUninstaller "$EXEDIR\uninst.exe"

>SectionEnd 

>

When I run the generated uninstaller, it shows the message box I defined, which means my custom functions is called successfully, but there's no checkbox on confirm page. At first I thought that it might be hiddden for some reason, but Spy++ reveals there's no such control created on the page. Am I missing something essential?

Yes :)
You need to use nsDialogs to create WHOLE uninstall page!
Usign ${NSD_CreateCheckbox} somewhere in code is not enough.

Creating page should look like this:

nsDialogsPage

    nsDialogs::Create 1018

    Pop $Dialog


   ${If} $Dialog == error

        Abort

    ${EndIf}

${NSD_CreateCheckbox} 50% 50% 100% 10u "&My checkbox"

    Pop $unCheckbox 


    nsDialogs::Show

FunctionEnd

But there is more to do, see docs: http://nsis.sourceforge.net/Docs/nsDialogs/Readme.html

That's mighty strange, because MUI2 readme clearly states the following:
"Modern UI pages can also be customized using custom functions."
and
"nsDialogs allows you to create custom pages or customize existing pages directly from the script."
And this is true, at least partially ;) I was able to customize uninstaller finish page this way:

define name customfinish

>!include "MUI2.nsh"

>!include "FileFunc.nsh"


>OutFile      "${name}.exe"

>Name         "${name}"

>InstallDir   "$TEMPDIR"


>var unCheckbox


>Function un.MyFinishShow

    MessageBox MB_OK "Showing finish page"

   ${NSD_CreateCheckbox} 50% 50% 100% 10u "&My checkbox"

    Pop $unCheckbox

    SetCtlColors $unCheckbox "" "ffffff"

>FunctionEnd

>!insertmacro MUI_UNPAGE_INSTFILES

>!define MUI_PAGE_CUSTOMFUNCTION_SHOW un.MyFinishShow

>!define MUI_FINISHPAGE_RUN ; -- Strange, but this is REQUIRED to have any controls shown on Finish page.

!insertmacro MUI_UNPAGE_FINISH

Naturally I thought this would be the way to modify uninstall Confirm page as well, but it seems it's not the case, so I decided to seek help here. I really don't want to reinvent the wheel (i.e. recreate the whole page) just to add a checkbox to one of pages existing by default :)

I actually solved the problem by following "Option A" solution found here.
