Upgrading GFI LanGuard to the Latest Software Version

Author: Andriy Rybalchenko Updated

Overview

The purpose of this article is to provide information about the upgrade paths and describe the required steps as to how to download the latest build and upgrade GFI LanGuard to the latest version.

 

Solution

Since updated definitions are provided only to the latest version, we recommend upgrading your LanGuard considering the upgrade paths below.

Upgrade Path Notes

The correct process for upgrading while retaining your settings depends on the GFI LanGuard currently installed version. First, select your upgrade path based on your current version of GFI LanGuard. Once you determined your upgrade path, please study the important notes from the corresponding link:

(Recommended) Backup LanGuard

It is recommended to backup your current GFI LanGuard database, the GFI LanGuard Data directory, and export the GFI LanGuard settings before an upgrade, as described in Backing Up GFI LanGuard. This backup may be useful in case the upgrade fails.

Upgrade Procedure

Ensure the GFI LanGuard server meets the system requirements, cryptographic protocol TLS 1.1 or above is running, and FIPS-Compliant algorithms are enabled in the local policy.

LanGuard works in environments with TLS 1.0 too, but this protocol is outdated and not recommended due to security considerations.

Once ready, proceed with the upgrade steps below:

  1. Log on to your current GFI LanGuard server as an Administrator or use an account with administrative privileges.

  2. Click Download Upgrade to download the latest build on the server where GFI LanGuard is currently installed. Alternatively, download the latest build manually.

  3. Right-click the newly downloaded installer and choose Properties.

  4. From the General tab, click Unblock and then Apply. This step is required to prevent the operating system from blocking certain actions by the installer.

  5. Disable anti-virus software on the server machine during the upgrade installation. Re-enable it once the upgrade is complete.

  6. Launch the installer.

  7. In the components screen, select GFI LanGuard to install a local server instance. You may optionally choose GFI LanGuard Central Management Server to install a central server instance. Install only one instance of the Central Management Server within your organization.

  8. In the Username and Password fields, enter your GFI Accounts area credentials or the account used when signing up to download GFI LanGuard. Click Sync to retrieve the license keys registered to your account. Choose a key from the Available keys drop-down.

    Alternatively, manually specify a license key in the Enter license key field.

  9. After specifying your account's license key, the wizard prompts you to choose an existing Microsoft SQL Server or SQL Express. If a current installation is not available, click the option to install Microsoft SQL Express (free) on the local server. Proceed with the Microsoft SQL Express 2012 wizard.

  10. Follow the wizard steps to install the new version side-by-side to your old version.

  11. When launching GFI LanGuard for the first time, you will be asked to import the old instance's configuration. Choose the settings to import and click Next.

Note: Agents normally will be updated at the start of the next agent scanning operation.

 

Testing

When the import has been completed, test the upgrade by running a scan to ensure GFI LanGuard is installed successfully. When the new version has been confirmed to be operational, you may uninstall the old version from Windows Programs and Features.
