GFI LanGuard Installation

Author: Sami Mohamad Updated

Overview

This article covers the GFI LanGuard Installation component. After reviewing this article, you will:

  • Know on which operating systems LanGuard can be installed.
  • Understand the installation process for LanGuard.
  • Know how to locate the installation logs and be able to identify common issues encountered when installing LanGuard. 

Introduction

The installation of the GFI LanGuard is pretty straightforward, as long as all the system requirements are met. Moreover, for the new versions of LanGuard, the upgrade process is practically the same as the installation. 

When you install a new major version for any GFI Software Solution, a new license key is required. In GFI LanGuard’s case, LanGuard 11 (i.e., LanGuard 2015) license keys do not work with LanGuard 12, but a license for LanGuard 12 will work for any build of LanGuard 12. 

Note: GFI Technical Support does not offer installation services. We expect our users to try the installation themselves, and if they run into issues, we would troubleshoot from there.

Description

System Requirements for GFI LanGuard

GFI LanGuard can only be installed on a Windows operating system. Computers running GFI LanGuard must meet the system requirements described in GFI LanGuard system requirements for performance reasons. Please review the above-linked article in its entirety. 

 

Steps to Install GFI LanGuard

You may be aiming to install multiple LanGuard servers and, as such, need the CMS (Central Management Server) to be installed to combine the list of devices for reporting purposes. The below-linked articles will assist in planning the deployment of the LanGuard installation.

Locating the Installation Logs for GFI LanGuard

Sometimes, things go wrong during the installation process. When this happens, you can troubleshoot to understand what went wrong. Installation logs that GFI LanGuard generates are located in the C:\Users\<USERNAME>\AppData\Local\Temp . HereUSERNAME is the user account logged in at the time of installation.

Occasionally, you may find the logs in a numbered subfolder, rather than directly in Temp (such as Temp\2).

Refer to the table below for the log contents of each log file. The exact file name may change according to the installation version, for example, v127 correlates to LanGuard 12.7.

Common Issues When Installing GFI LanGuard

Our installation logs follow standard System Error Codes as per Microsoft. 

 

 

 

Often, the GFI LanGuard installer does a reasonably decent job of calling out what the error is. Sometimes though, you will need to know where to find these files and to investigate what is causing the issue with the new install/upgrade.

  • File Location: lanss_v127_languardsb.csv 
  • Error:

    2018-10-25,09:52:49,522,"#00002d54","#000041d0","error ","Database connection error. SqlState is 08001. NativeError is 18. Msg is [Microsoft][ODBC SQL Server Driver][Shared Memory]SSL Security error" 

    2018-10-25,09:52:49,523,"#00002d54","#000041d0","error ","Database connection error. SqlState is 01000. NativeError is 772. Msg is [Microsoft][ODBC SQL Server Driver][Shared Memory]ConnectionOpen (SECDoClientHandshake())."

The above is an example message you might encounter. This error is due to the TLS (Transport Layer Security) connection not working correctly. In the above example, the SSL connection is failing. In this specific instance, TLS 1.2 was enabled, but the FIPS (Federal Information Processing Standards) algorithm that we require to be enabled in Windows was not.

    2019-02-21,17:29:19,571,"#00000c9c","#00000c98","info ","StringResources::GetString - string found:'SQL database name:'"

In the above error, the ‘admin’ user account does not have permissions to the SQL Database.

    2019-02-21,17:38:00,400,"#00000c9c","#00000c98","info ","StringResources::GetString - string found:'SQL database name:'"

In the above error, the SQL instance was wrong which caused the SQL Database not to be found.
