hide & disable RUN Checkbox in the finish Page of MUI

Hello

I'd like to disable (hide & uncheck) the Run checkbox in the finishpage of a MUI installer during runtime.

can somebody tell me what im doing wrong?

the following code doesn't do a thing
The GetdlgItem always return '0'🧟
Somebody have some hints what I'm doing wrong?

!define MUI_PAGE_CUSTOMFUNCTION_SHOW Show_PageFinish_custom

!insertmacro MUI_PAGE_FINISH

Function Show_PageFinish_custom

    GetDlgItem $R9 $MUI_HWND 1203 ; run checkbox, see MUI_FINISHPAGE_RUN_TEXT macro

    ShowWindow $R9 ${SW_HIDE}

   MessageBox MB_OK $R9  

#    MessageBox MB_OK $MUI_HWND

FunctionEnd

Why? Why not just not use MUI_FINISHPAGE_RUN?
Instead execute your file in the page's leave function.

I have the same installer vor Admin and non Admin

If a admin installs he can choose to run the helper programm at the end

If a non admin installs, he must not run the helper programm...

How about disable?

I had a similar thing where I needed to disable the check box on the final page rather than hide it.

I have some variable, which I called $MYVAR in this example here. This is set earlier on in the installer depending on a certain condition. You the define the function to be called before the final page is displayed:

!define MUI_PAGE_CUSTOMFUNCTION_PRE "FinalPagePre"

This function sets the Flag of Field 4 (which should be the first check box on the final page if I recall correctly),

Function FinalPagePre

  ${If} $MYVAR == "true"

  !insertmacro MUI_INSTALLOPTIONS_WRITE "ioSpecial.ini" "Field 4" "Flags" "DISABLED"

  ${EndIf}

FunctionEnd

There are more details in "NSIS\Docs\Modern UI\Readme.html"

Your code to hide the check box should work if you have the control id correct. It is 1200 + field number - 1.
If you get to the finish page then look at %TEMP%\ns###.tmp\ioSpecial.ini you can find out which field is the check box (it's an InstallOptions initialisation file).

thanks !

It's easier to read the HWND field, see the InstallOptions readme.
