Update your Lansweeper Classic installation regularly to get the latest patches and any newly released features. Updates are free with an active Lansweeper license. They install over your existing installation and leave your data and settings intact, so you never need to reinstall.
You can check whether you have the latest Lansweeper version from the web console. On a medium sized network, the update itself takes a few minutes.
Lansweeper can update itself. See Enable the Lansweeper scan server to auto-update if you'd rather not update manually.
Before you update
Check your current version is supported
Lansweeper 4.0 and later can be updated straight to the latest version. Updates from 1.x, 2.x, and 3.x releases are not supported. If you're on one of those releases, archive your installation for future reference and perform a new installation of the latest version instead.
Check the .NET requirement
Every computer hosting the scanning service or web console component needs .NET Framework 4.8. This is a requirement from Lansweeper 8.2.200 onward.
If you're not sure which machines host the Lansweeper service, they're listed in the Current Version section of the Configuration > Your Lansweeper License page.
Installer version 8.2.200 and newer pauses to install .NET 4.8 automatically on systems that don't have it. If you get a reboot message at the end of the installer, reboot before using Lansweeper. Your components aren't functional until you do.
Back up your installation
Back up your installation before you start. If the update fails, the backup is your way back.
Update the service, database, and console
If the Upgrade option is grayed out, you're either not running the latest installer or you're already on the latest version. Don't continue. Select Cancel to close the installer.
If your database is hosted in an Express edition of Microsoft SQL Server with less than 300 MB free, the installer clears the tables holding Windows event log data to make room. These tables are usually the largest. Express editions of SQL Server 2008 R2 and later are capped at 10 GB by Microsoft; older Express editions are capped at 4 GB.
-
Download the latest Lansweeper installer and run it on a machine hosting the Lansweeper Server service.
If your database is hosted on a different machine than the Lansweeper service, you don't need to run the installer on the database machine. The Lansweeper service updates your database automatically.
-
Select Next and review the terms of use, which you must accept to proceed.
-
Select the Upgrade option, then select Next.
-
The installer detects which components need updating. Select Next to continue.
-
The installer updates the Lansweeper service, the Lansweeper database, and the web console if it's hosted on the same machine.
-
Select Finish to close the installer.
Update your other Lansweeper servers
Run the installer on every remaining machine that hosts a Lansweeper component:
- Web console on a separate machine. Run the installer on that machine and go through the same update procedure.
- Multiple machines hosting the scanning service. Run the installer on each one, or use the installer parameters described in Silently install, uninstall, or update Lansweeper.
Update your scanning agents
- LsPush. Copy the up-to-date LsPush to any folder referenced by your logon script, group policy, or scheduled task. After the update, the latest LsPush executable is in
Program Files (x86)\Lansweeper\Clienton your Lansweeper server. - LsAgent. LsAgent installations don't auto-update. Update them on the machines you're scanning. The latest installers are on the LsAgent download page.
If the update fails
Restore your installation from a backup, then collect files for Lansweeper Support so support can work out what went wrong.
