NSIS静默安装(通过代码启动)

Question

我正在尝试构建一个NSIS安装程序,它将执行以下操作:

1当正常运行时,它将使用具有常规选项的安装程序安装应用程序.

2当使用/ S开关运行安装程序时,它会进行静默安装,如果它显示UI则没问题.但它应该是自动的.

在我看来,安装程序"工作",因为它运行,然后再次正确启动应用程序.但它没有更新任何东西,它几乎就像它运行,但不复制任何文件.

当它是静默安装时,它由以下代码启动(应用程序更新自身)

    ProcessStartInfo Pro = new ProcessStartInfo();
    Pro.Verb = "runas";
    Pro.UseShellExecute = true;
    Pro.FileName = gDownloadedFileName;
    Pro.Arguments = "/S";
    Pro.WindowStyle = ProcessWindowStyle.Normal;
    Pro.CreateNoWindow = true;

NSIS脚本主(我可以发布NSIS的支持脚本,如果ppl需要自定义)

; example2.nsi
;
; This script is based on example1.nsi, but it remember the directory, 
; has uninstall support and (optionally) installs start menu shortcuts.
;
; It will install example2.nsi into a directory that the user selects,
!include MUI.nsh
!include fileassoc.nsh
!include Silent.nsh

Answer 1

StrCmp $ 0 1 0 +3是错误的,它应该是+2(在这个例子中+3可能是未定义的行为,因为你正在跳过隐藏的返回指令).

使用相对跳转很容易出错,您应该使用标签或使用逻辑库重写它:

!include LogicLib.nsh
...
Function .onInit
  Call GetDotNet

  ${If} ${Silent}
    call SilentInstall
  ${EndIf}
FunctionEnd

但是,当正常安装逻辑几乎相等时,将静默安装逻辑放在一个单独的函数中会使工作量增加一倍.您应该能够删除SilentInstall函数,并在静默安装期间使用隐藏部分执行:

Section "${_AppName} (required)"
#shared install code
SectionEnd

Section "Start Menu Shortcuts"
#shared startmenu code
SectionEnd

Section
${If} ${Silent}
    Exec ${_AppExe}
${EndIf}
Section

很难说为什么你的文件没有更新,但如果你使用共享代码,你可以在没有/ S的情况下运行它并检查详细日志.我唯一的猜测是,InstallDirRegKey正在选择一个非默认的installdir而你正在查看错误的文件.您可以使用Process Monitor来监视安装.

您的代码还有其他一些不相关的问题:

• RequestExecutionLevel管理员是不够的,你需要处理NT5和NT6与UAC关闭(UserInfo :: GetAccountType)
• 当图标与目标程序相同时,您不必指定快捷方式图标
• 在调用Exec时应该引用路径: Exec '"$instdir\${_AppExe}"'
• 将UAC/runas/RequestExecutionLevel管理员与Exec混合是有问题的,因为您可能最终以错误的用户身份运行程序.
