Inno设置-如果将设置设置为PrivilegesRequired = lowest，如何使用管理员权限运行复制? [英] Inno Setup - How to run an aplication with admin privileges if the setup is set to PrivilegesRequired=lowest?

问题描述

我想使用 PrivilegesRequired = lowest 运行安装程序.如何设置和运行应用程序(dxwebsetup.exe)以具有管理员权限的安装程序进行安装?

I want to run the setup with PrivilegesRequired=lowest. How to set and run an application (dxwebsetup.exe) to install with my setup with Administrator privileges?

我的代码( Inno设置-避免显示子安装程序的文件名):

procedure CurStepChanged(CurStep: TSetupStep);
var
  ProgressPage: TOutputProgressWizardPage;
  ResultCode: Integer;
begin
  if CurStep = ssInstall then
  begin
    if IsComponentSelected('DirectX') then
    begin
      ProgressPage := CreateOutputProgressPage('Installing prerequsities', '');
      ProgressPage.SetText('Installing DirectX...', '');
      ProgressPage.Show;
      try
        ExtractTemporaryFile('dxwebsetup.exe');
        StartWaitingForDirectXWindow;
        Exec(ExpandConstant('{src}\_Redist\dxwebsetup.exe'), '', '', SW_SHOW,
             ewWaitUntilTerminated, ResultCode);
      finally
        StopWaitingForDirectXWindow;
        ProgressPage.Hide;
      end;
    end;
  end;
end;

推荐答案

使用 <代码> ShellExec 和 runas 动词，而不是 Exec :

ShellExec('runas', ExpandConstant('{src}\_Redist\dxwebsetup.exe'), '', '', SW_SHOW,
          ewWaitUntilTerminated, ResultCode);

当当前的Inno Setup进程在没有管理员权限的情况下运行时，您将看到UAC提示.

When the current Inno Setup process runs without Administrator privileges, you will get a UAC prompt.
