NSIS。强制退出安装程序

Question

我定义了自定义中止功能，并希望退出安装程序。

!define MUI_ABORTWARNING
!define MUI_CUSTOMFUNCTION_ABORT customOnUserAbort

Function customOnUserAbort
    Quit (or Abort) #no matter
FunctionEnd

此外，我还有一个自定义页面，可以在MyCustomLeave（离开页面时）功能的后台执行长时间程序

Function MyCustomLeave
    ShowWindow $UnderTopLabel 0
    ShowWindow $UnderTopLabel2 1

    EnableWindow $CustomNext.Button 0

    EnableWindow $RADIO1 0
    EnableWindow $RADIO_LABEL1 0
    EnableWindow $RADIO2 0
    EnableWindow $RADIO_LABEL2 0
    ShowWindow $GROUP1 ${SW_HIDE}

    ${NSD_LV_GetCheckState} $GROUP1 $unpackIndex $Checkbox_StateUnpackIndex

    ${NSD_LV_GetCheckState} $GROUP1 $hpIndex $Checkbox_StateSetUpHomepage
     ${if} $Checkbox_StateSetUpHomepage == 1
        StrCpy $ChangeHomepage 1
     ${else}
        StrCpy $ChangeHomepage 0
     ${endif}

    ${NSD_LV_GetCheckState} $GROUP1 $searchIndex $Checkbox_StateSetUpSearch
     ${if} $Checkbox_StateSetUpSearch == 1
        StrCpy $ChangeSearch 1
     ${else}
        StrCpy $ChangeSearch 0
     ${endif}

    ${NSD_LV_GetCheckState} $GROUP1 $ntIndex $Checkbox_StateSetUpNewTabPage
     ${if} $Checkbox_StateSetUpNewTabPage == 1
        StrCpy $ChangeNewTabPage 1
     ${else}
        StrCpy $ChangeNewTabPage 0
     ${endif}

     /*CUSTOM_PAGE_SOFT_3*/

    Call ValidateCheckedExtraSoft

    GetFunctionAddress $0 **workerfunc**
    BgWorker::CallAndWait #in background
FunctionEnd

当我点击右上角的十字按钮时，会调用customOnUserAbort函数并打开一个新的清除灰色窗口，但在 workerfunc 完成之前，安装程序不会退出。

如何强制退出安装程序？或者如何禁用红十字按钮？ 请帮帮我。

感谢。
