我可以找到某个实际的订单，在卸载期间执行哪些事件和部分？例如，UninstallDelete会比usPostUninstall卸载步骤更早出现吗？
Inno Setup在手册中有“安装顺序”一文，但它看起来更像是编译顺序，而不是执行。
卸载顺序与installation order相反，正如手册所说（它实际上是安装顺序，而不是编译顺序）。
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)InitializeUninstallProgressFormCurUninstallStepChanged(usUninstall)[UninstallRun]
注册表项
图标
档
应用目录
[UninstallDelete]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）：
