When the GFI LanGuard fails to install or upgrade correctly, or its components become corrupted, the following errors may appear:
- Console and Services do not start or unexpectedly stop
- Tasks fail to run
- Some console components do not update the information
- Program Updates constantly failing
- Some results do not load after the scan/remediation job
- Constant exceptions and crashes in logs
- Components not registered or missing files
This article provides information on how to repair GFI LanGuard.
Note: If you are experiencing problems only with scanning or remediation operations, first Test Network Connectivity and Security Permissions for GFI LanGuard Operations and check our Knowledge Base for the specific errors you encounter.
The most common root cause for the failed installations or upgrades cases is not meeting all the prerequisites and requirements. For example, not disabling antivirus software before the deployment, using an account with not enough local administrative privileges, running applications, etc.
For the already running installation, it is possible for components to become corrupt due to changes in the environment.
Note: If you are experiencing problems with program updates or scanning operations not detecting expected patches, it may be that your LanGuard version is old - updated definitions are only provided to the latest versions of the product. Therefore it is recommended to always upgrade to the most recent version.
This best solution for fixing the GFI LanGuard components is using the Repair option in the Programs and Features applet (in the Windows Control Panel).
Before repairing the installation:
- Ensure that the machine where GFI LanGuard is going to be installed meets the system requirements.
- Configure the firewall to allow GFI LanGuard to connect to GFI servers and to the remote machines to be monitored.
- Disable third-party antivirus during the installation process.
- Save any pending work and close all open applications on the machine.
- Log on to the GFI LanGuard server as an Administrator or user with administrative privileges.
- Download the installer for the currently installed GFI LanGuard version:
- Right-click on the installer > Properties > Unblock > Apply before running the installation.
- Double-click on the LanGuard installer to run the installer and wait for the first wizard windows.
- Go to the
Tempfolder created – typically
C:\Users\<logged on user>\AppData\Local\Temp\2\LanGuard12Resources.
- Copy this folder to the desktop and cancel the installer.
- Run the Repair option from Programs and Features in Control Panel and point the repair to the folder that was copied in the previous step.
Run the GFI LanGuard and check the operations that were failing before.
Or, if this is your first installation, GFI LanGuard will automatically start a scan of the local computer for vulnerabilities when launched for the first time. On completion, the GFI LanGuard Console Home page displays the vulnerability scan result.
