NSIS静默安装(通过代码启动)

本文关键字：代码 启动 静默 安装 NSIS | 更新日期: 2023-09-27 17:55:06

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，它将使用带有通常选项的安装程序安装应用程序。

2当安装程序使用/S开关运行时，它是静默安装，如果它显示UI是可以的。但它应该是自动的。

在我看来，安装程序"工作"，因为它运行，然后正确地再次启动应用程序。但是它没有更新任何东西，它几乎就像在运行一样，但不复制任何文件。

当它是静默安装时，它由以下代码启动(应用程序更新自己)

    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(如果ppl愿意，我可以发布自定义的NSIS支持脚本)

; 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,

NSIS静默安装(通过代码启动)

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，因为你跳过了隐藏的返回指令)。

使用相对跳转容易出错，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单独的函数中会使工作加倍。您应该能够删除SilentInstall函数，并在静默安装期间只使用隐藏部分来执行:

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，但是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正在挑选一个非默认的安装目录，你正在看错误的文件。您可以使用Process Monitor来监视安装过程。

你的代码有一些其他不相关的问题:

  • RequestExecutionLevel admin是不够的，你需要处理NT5和NT6与UAC关闭(UserInfo::GetAccountType)
  • 当快捷图标与目标程序相同时，您不必指定快捷图标
  • 调用Exec: Exec '"$instdir'${_AppExe}"'
    • 时应该引用路径
  • 混合UAC/runas/RequestExecutionLevel admin与Exec是有问题的，因为你最终可以运行程序作为错误的用户。

这是一个棘手的问题。我使用相同的方法来更新我的应用程序，静默地调用NSIS安装程序。在我的例子中，问题不在于NSIS脚本，而是我使用WebClient类将包含我的安装程序的zip文件下载到临时目录，然后在那里提取它，并从那里运行它。问题是，ZipFile类生成一个异常，如果提取的安装文件存在，因此旧的安装程序仍然存在，除了卸载可执行文件外，程序目录中没有更新任何内容。

对我来说，解决方案是在下载新文件(在VB.NET中)之前清理旧的zip和exe文件:

    If File.Exists(Path.Combine(Path.GetTempPath(), "Setup.zip")) Then
        File.Delete(Path.Combine(Path.GetTempPath(), "Setup.zip"))
    End If
    If File.Exists(Path.Combine(Path.GetTempPath(), "Setup.exe")) Then
        File.Delete(Path.Combine(Path.GetTempPath(), "Setup.exe"))
    End If
