在Inno Setup中进行安装之前，先检测重启是否挂起 [英] Detect if restart is pending before installing in Inno Setup

问题描述

如果重新启动/重新启动已经挂起/需要，是否可以防止安装?

Is there a way to prevent installation if a reboot/restart is already pending/required?

我们的安装程序安装了SQL Server Express，并且如果系统中有挂起的重新启动，有时它会拒绝这样做. Inno Setup可以检测到这种情况，以便在安装我们的软件之前告诉用户重新启动吗?

Our setup installs SQL Server Express and it will sometimes refuse to do so if there is a pending restart in the system. Can Inno Setup detect this condition so I can tell the user to reboot before installing our software?

我了解 MakePendingFileRenameOperationsChecksum ，但是通常提到它检测在安装过程中是否出现要求重新启动的条件.可以在使用之前吗?

I know about MakePendingFileRenameOperationsChecksum but it's usually mentioned to detect whether the reboot required condition appeared DURING the setup. Can it be used BEFORE?

推荐答案

如果要检测是否存在需要重新启动的挂起重命名，请查询PendingFileRenameOperations注册表值.

If you want to detect, if there is a pending rename that requires a restart, query PendingFileRenameOperations registry value.

另请参阅如何确定我刚刚安装的MSI是否要求Windows重新启动?

function IsRestartPending: Boolean;
var
  S: string;
begin
  if RegQueryMultiStringValue(
       HKLM, 'SYSTEM\CurrentControlSet\Control\Session Manager',
       'PendingFileRenameOperations', S) then
  begin
    Log(Format('PendingFileRenameOperations value exists with value [%s]', [S]));
    Result := (Trim(S) <> ''); { This additional check is probably not needed }
  end
    else
  begin
    Log('PendingFileRenameOperations value does not exist');
    Result := False;
  end;
end;

function InitializeSetup(): Boolean;
begin
  if IsRestartPending then
  begin
    MsgBox('Restart your machine please', mbError, MB_OK);
    Result := False;
    Exit;
  end;

  Result := True;
end;

如果您需要测试可能需要重新启动的其他操作，则必须使用@Jerry修改答案以设置Inno.
