Lansweeper Classic is agentless. You install it on one computer, which scans your entire network, and no additional software is needed on the machines you're scanning. Two scanning agents ship with the software, but both are optional. See LsPush vs LsAgent scanning agent for the difference.
Lansweeper scans Linux, Unix, Mac, and Windows computers, VMware servers, and other network devices, but must be installed on a Windows computer.
Architecture
64-bit, x64 architecture.
If your Lansweeper installation runs on a 32-bit server, you can move your installation to a different server.
Virtual or physical
You can install Lansweeper on either a virtual or a physical computer.
Operating system
You can install Lansweeper on non-Home, non-Core, and non-Starter editions of any operating system listed below. A Windows Server OS is recommended for networks of more than 1,000 assets, though not strictly required.
- Windows 10 21H2 (LTSC) or higher, with the exception of:
- Windows 10 1809 (LTSC)
- Windows 10 1607 (LTSB)
- Windows 10 1507 (RTM) (LTSB)
- Windows 11
- Windows Server 2016 (end of mainstream support; extended support available until January 12, 2027)
- Windows Server 2019 (end of mainstream support; extended support available until January 9, 2029)
- Windows Server 2022
- Windows Server 2025
Disk space
Lansweeper data, reports, and settings are stored in a database, hosted in either Microsoft SQL LocalDB, Microsoft SQL Server, or the deprecated Microsoft SQL Compact database server.
Database size varies a lot depending on how much data you scan and how much history you keep. As a general rule, reserve 1 GB of disk space per 1,000 Windows computers. Non-Windows machines have less impact on database size.
Database server
The database servers below are supported for hosting the Lansweeper database. Only SQL Server versions installed on a Microsoft Windows operating system are supported.
- Microsoft SQL LocalDB
- Microsoft SQL Server 2016, any edition (Express, Standard, Enterprise, and so on) including Cumulative Update 11 or higher
- Microsoft SQL Server 2017, any edition, including Cumulative Update 18 or higher
- Microsoft SQL Server 2019, any edition, including Cumulative Update 2 or higher
- Microsoft SQL Server 2022, any edition
- Microsoft SQL Server 2025, any edition
Microsoft SQL Server 2014 is only supported on Lansweeper 11.2.2.0 and earlier.
Lansweeper doesn't support Azure SQL Managed Instance as a database provider.

Web browser
Lansweeper has a web interface you can view in a browser, locally from the Lansweeper server or remotely from other machines. The browsers below are officially supported. Others may work as well, especially Chromium-based ones, but they haven't been tested for layout issues and may not be able to run asset or user actions.
- Google Chrome, updated to the latest version
- Mozilla Firefox, updated to the latest version
- Opera, updated to the latest version
- Microsoft Edge, updated to the latest (Chromium-based) version
The minimum supported screen resolution for viewing the Lansweeper interface is 1280 x 720 pixels, across all supported browsers.
Other installed software
- The computer you install Lansweeper on must have .NET Framework 4.8, updated to the latest service pack.
- The computer you install Lansweeper on must have Windows Installer 2.0.
- If you run an old Lansweeper version with SQL Compact as your database server, Visual C++ 2012 is also required. SQL Compact is no longer supported or offered as a database server option. If you still use it, convert your database to SQL LocalDB or SQL Server.
If you don't already have .NET Framework 4.8, the Lansweeper installer tries to download and install it for you. On a machine without internet access, you may have to download and install it manually. A reboot of your Lansweeper server may be required afterwards, whether it's installed manually or automatically.
Network requirements
Lansweeper needs specific ports open to scan your network and for its components to talk to each other. See ports scanned or used by Lansweeper.
