inno-setup – 卸载顺序

这只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,卸载程序只是以相反的顺序处理日志,而无需任何更改顺序的选项.

event functions适合卸载过程如下(仅显示主要的卸载步骤)：

> 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]

>第二次尝试删除目录(例如之前尚未为空的目录)
> CurUninstallStepChanged(usPostUninstall)
> CurUninstallStepChanged(usDone)
> DeinitializeUninstall

我在一个简单的安装程序上测试了这个：

[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;

卸载程序日志就像(它没有显示所有步骤)：
