This manual is for LISTSERV Classic running under Microsoft Windows.  LISTSERV Lite users should see the installation guide written specifically for LISTSERV Lite.

This manual makes the following assumptions:

      1. You have a supported Microsoft Windows operating system installed and operating normally on a computer in your network that meets the various technical requirements listed later in this guide;
      2. You have physical access to the machine in question and are logged in as Administrator, or at least as a member of the Administrators group with full control of the machine;
      3. You can troubleshoot your supported version of Microsoft Windows (i.e. native OS problems, not problems related to LISTSERV) without assistance from this guide or from L-Soft.

Number three is particularly important.  L-Soft will be happy to assist you with LISTSERV-related problems arising under a supported version of Microsoft Windows (assuming of course that you have purchased support for our product) but is unable to assist you in setting up your operating system, the Internet Information Service (or any other web server software available for the supported Microsoft Windows operating systems), or any aspect of your operating system that is not directly related to LISTSERV's operation.  If you are not familiar with Microsoft Windows operating systems, please be aware that L-Soft cannot help you with either their installation or subsequent troubleshooting.

This manual also follows this convention:

"Windows" or "the Windows operating system" means the Microsoft Windows Server and Workstation operating system versions currently supported by L-Soft.  In other words, if we say "Windows", we mean "all of the Microsoft Windows operating systems under which LISTSERV is currently supported".

"Windows Server" means specifically the Microsoft Windows Server operating systems which are currently supported by L-Soft.

"Windows Workstation" means specifically  the Microsoft Windows workstation operating systems which are currently supported by L-Soft.

If we indicate a specific Microsoft Windows operating system by name, for example, "Windows 10", we mean specifically that version of the operating system and no other.

At the release date of LISTSERV 17.5, the following Microsoft Windows operating systems were supported by L-Soft for use with LISTSERV:


L-Soft LISTSERV 17.5 Supported Microsoft Windows Operating Systems

LISTSERV for Microsoft Windows

Windows 10 (64-bit only)


Windows 11 (64-bit only)


Windows Server 2016


Windows Server 2019


Windows Server 2022


Support for 32-bit Microsoft Windows operating systems was withdrawn by L-Soft as of version 16.0-2017a.

Support for 64-bit Microsoft Windows operating system versions will be withdrawn by L-Soft as the specific version reaches end of life, as published in the Microsoft Lifecycle Policy.

While LISTSERV will run on Microsoft's currently-supported workstation operating systems, L-Soft strongly recommends the use of Windows Server wherever possible.

LISTSERV for Microsoft Windows is being run successfully on Windows Server 2019 and 2022 virtual machines running under the Microsoft Hyper-V hypervisor, including on Microsoft's Azure cloud server service.
