Inno Setup - 卸载注册表删除选项

Question

程序我正在构建一个安装程序,使用注册表项来存储用户设置.现在我已将它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,因此答案越简单越好.

我的注册表/卸载目前看起来像这样.

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


    [UninstallDelete]

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密钥(以某种有意义的消息方式)并手动删除密钥.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.你可以遵循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;
