卸载顺序 [英] Uninstallation order

问题描述

我可以在卸载期间执行事件和节的实际顺序中找到某个地方吗?例如，UninstallDelete是否会比usPostUninstall卸载步骤更早出现?

Can I find somewhere actual order, in which events and sections are executed during uninstall? For example, will UninstallDelete occur earlier than usPostUninstall uninstall step?

Inno Setup在手册中有安装顺序"文章，但看起来更像是编译顺序，而不是执行顺序.

Inno Setup has "Installation order" article in manual, but it looks more like compilation order, not execution.

推荐答案

卸载顺序与安装顺序(实际上是安装顺序，而不是编译顺序).

The uninstallation order is an opposite of the installation order, just as the manual says (and it is really the installation order, not a compilation order).

这仅仅是因为没有编程的卸载顺序.安装程序将其步骤记录到卸载日志中，并且卸载程序仅以相反的顺序处理日志，而没有任何更改顺序的选项.

It's simply because there's no programmed uninstallation order. The installer records its steps into uninstall log and the uninstaller just processes the log in an opposite order, without any option to alter the order.

事件函数适用于卸载过程，如下所示(仅主要显示的卸载步骤):

The event functions fit in the uninstallation process as follows (only major uninstallation steps shown):

• CurUninstallStepChanged(usAppMutexCheck)
• InitializeUninstallProgressForm
• CurUninstallStepChanged(usUninstall)
• 处理卸载日志:
  • [UninstallRun]
  • 注册表项
  • 图标
  • 文件
  • 应用程序目录
  • [UninstallDelete]
  • CurUninstallStepChanged(usAppMutexCheck)
  • InitializeUninstallProgressForm
  • CurUninstallStepChanged(usUninstall)
  • Processing the uninstall log:
    • [UninstallRun]
    • registry entries
    • icons
    • files
    • application directory
    • [UninstallDelete]

    我已经在一个简单的安装程序上对此进行了测试:

    I've tested this on a simple installer:

    [Setup]
    AppName=My Program
    AppVersion=1.5
    DefaultDirName={pf}\My Program
    DefaultGroupName=My Program
    UninstallDisplayIcon={app}\MyProg.exe
    OutputDir=.
    
    [Files]
    Source: "MyProg.exe"; DestDir: "{app}"
    
    [Icons]
    Name: "{group}\My Program"; Filename: "{app}\MyProg.exe"
    
    [UninstallRun]
    FileName: "{app}\MyProg.exe"
    
    [UninstallDelete]
    Type: files; Name: "{app}\test.dat"
    

    [Code]
    
    function InitializeUninstall(): Boolean;
    begin
      Log('InitializeUninstall');
      Result := True;
    end;
    
    procedure InitializeUninstallProgressForm;
    begin
      Log('InitializeUninstallProgressForm');
    end;
    
    procedure DeinitializeUninstall;
    begin
      Log('DeinitializeUninstall');
    end;
    
    procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep);
    begin
      Log('CurUninstallStepChanged + ' + IntToStr(Integer(CurUninstallStep)));
    end;
    

    卸载程序日志类似于(它不会显示所有步骤):

    The uninstaller log is like (it does not show all the steps):
