В: Можно ли сделать поиск в реестре из инсталлятора?

Спойлер: О: Конечно

var
  SearhBtn: TNewButton;
  SearhEdt: TNewEdit;

function SReg(Root: Integer; Key, mask: string): string;
var
  i: Integer;
  aos: TArrayOfString;
  s: string;
begin
  if RegGetSubkeyNames(Root, Key, aos) then
  for i := 0 to GetArrayLength(aos) - 1 do
  begin
    s := Key + '\' + aos[i];
    if pos(mask, aos[i])>0 then
    Result := Result+#13#10+s;
    SReg(Root, s, mask);
  end;
  if RegGetValueNames(Root, Key, aos) then
  for i := 0 to GetArrayLength(aos) - 1 do
  begin
    s := Key + '\' + aos[i];
    if pos(mask, aos[i])>0 then
    Result := Result+#13#10+s;
  end;
end;

procedure SearhBtnClick(Sender: TObject);
begin
  WizardForm.WelcomeLabel2.Caption :=
    SReg(HKLM64 , 'SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall',SearhEdt.Text);
end;

procedure InitializeWizard();
begin
  with WizardForm.WelcomeLabel2 do
  begin
    Height := ScaleY(207);
    Caption :='';
    WordWrap := True;
  end;
  { SearhBtn }
  SearhBtn := TNewButton.Create(WizardForm);
  with SearhBtn do
  begin
    Parent := WizardForm.WelcomePage;
    SetBounds(ScaleX(176), ScaleY(285), ScaleX(51), ScaleY(25));
    Caption := 'Searh';
    OnClick := @SearhBtnClick;
  end;

  { SearhEdt }
  SearhEdt := TNewEdit.Create(WizardForm);
  with SearhEdt do
  begin
    Parent := WizardForm.WelcomePage;
    SetBounds(ScaleX(232), ScaleY(287), ScaleX(121), ScaleY(21));
  end;
end;

P.S. Не советую делать таким образом поиск от корня реестра, это может затянуться надолго

В: Как проверить на наличие ключа в реестре?
О: Так:

Спойлер

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

function IsRegistryKeyExists(const RootKey: Integer; const SubKey: String): Boolean;
var
  Value: String;
begin
  // Пытаемся получить строковое значение из реестра
  Result := RegQueryStringValue(RootKey, SubKey, '', Value);
end;

// Пример использования
function InitializeSetup(): Boolean;
begin
  // Проверяем наличие ключа в реестре
  if IsRegistryKeyExists(HKEY_LOCAL_MACHINE, 'Software\YourCompany\YourProduct') then
  begin
    // Ключ существует, делаем что-то...
    MsgBox('Ключ найден!', mbInformation, MB_OK);
  end
  else
  begin
    // Ключ не существует, делаем что-то еще...
    MsgBox('Ключ не найден!', mbInformation, MB_OK);
  end;

  // Всегда возвращаем True, чтобы установка продолжилась
  Result := True;
end;
