Overview

On some systems, after upgrading to 12.11, the Attendant service does not run. Starting it shows the following message: "Error 1053: the service did not respond to the start or control request in a timely fashion."

When attempting to manually run the C:\Program Files (x86)\GFI\LanGuard 12 Agent\lnssatt.exe executable on such systems, the following error message occurs: "The code execution cannot proceed because mfc140u.dll was not found." This error prevents the Attendant service from starting. The missing mfc140u.dll file is part of the Microsoft Visual C++ Redistributable package.

Solution

To resolve this issue, install the required Visual C++ Redistributable package for Visual Studio. Follow the steps below:

1. Download the Visual C++ Redistributable 2015-2022 x86 package from Microsoft: Download link

2. Run the downloaded installer and follow the prompts to install the package.

3. After installation, attempt to start the LanGuard Attendant service again or rerun the lnssatt.exe executable. No error messages should pop up and nothing should appear to happen.

4. If the error persists, restart the machine to ensure that the installed redistributable files are correctly loaded.

5. If the issue persists post restart, reinstall the agent.

This should resolve the issue with the missing mfc140u.dll file, allowing the service to start successfully.
