我正在构建安装程序的程序使用注册表项来存储用户设置。现在，我将其设置为在卸载程序时删除所述注册表文件，但我希望能够为用户提供在卸载时保留或删除注册表文件的选项。

我不是最好的脚本编写者/程序员，所以答案越简单越好。

我的注册表/卸载当前看起来像这样。

    [Registry]
    Root: HKCU; Subkey: "Software\FFSPLIT Overlay Filter"; Flags: uninsdeletekey


    [UninstallDelete]  
    Type: filesandordirs; Name: "{app}\ffmpeg"
    Type: filesandordirs; Name: "{app}\OverlayData"
    Type: files; Name: "{app}\AForge.Controls.dll"

InnoSetup 没有任何条件卸载检查参数，因此您必须自己执行此操作。因此，您需要删除uninsdeletekey将自动删除注册表项的标志，并且在卸载过程结束时，您可以询问用户是否要删除该键（以某种有意义的消息方式）并手动删除该键。以下脚本在卸载后步骤执行此操作，即成功卸载应用程序的时间。您可以按照commented version：

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program

#define FilterRegKey "Software\FFSPLIT Overlay Filter"

[Registry]
Root: HKCU; Subkey: "{#FilterRegKey}"

[Code]
procedure CurUninstallStepChanged(CurUninstallStep: TUninstallStep);
begin
  if CurUninstallStep = usPostUninstall then
  begin
    if RegKeyExists(HKEY_CURRENT_USER, '{#FilterRegKey}') then
      if MsgBox('Do you want to delete the overlay filter registry key ?',
        mbConfirmation, MB_YESNO) = IDYES
      then
        RegDeleteKeyIncludingSubkeys(HKEY_CURRENT_USER, '{#FilterRegKey}');
  end;
end;
