NSIS静默安装（通过代码启动）

时间：2011-05-05 10:47:18

标签： c# installer nsis

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，它将使用具有常用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，如果显示UI则可以。但它应该是自动的。

在我看来，安装程序“正常”，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（应用程序自行更新）

    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main（我可以发布NSIS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,

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倍增。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的情况下运行它并查看详细日志。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Process Monitor监控安装。

您的代码还有其他一些不相关的问题：

  • RequestExecutionLevel admin是不够的，你需要处理NT5和NT6与UAC关闭（UserInfo::GetAccountType）
  • 当图标与目标程序相同时，您不必指定快捷方式图标
  • 您应该在致电Exec时引用路径：Exec '"$instdir\${_AppExe}"'
  • 将UAC / runas / RequestExecutionLevel管理员与Exec混合是有问题的，因为您最终可能会以错误的用户身份运行该程序。

答案 1 :(得分：0)

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，默默地调用NSIS安装程序。在我的情况下，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，然后在那里解压缩，然后从那里运行它。问题是如果提取的安装文件存在，ZipFile类会生成异常，因此旧的安装程序仍然存在，并且除了卸载可执行文件之外的任何内容都不会在程序目录中更新。

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

    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
