Download and Install Lasso 9 Server

This page briefly outlines the installation of Lasso 9 Server for each supported platform.

You can download Lasso 9 Server for FREE and run Lasso in "developer mode", which is fully functional but limited to 5 IP's and 200 connections per minute, so it will not support full deployment. Come back and buy the license to unlock its full power when you are convinced that Lasso gives you everything you need—and more!

Recommended reading before you install

Lasso 9 is a middleware product which relies on third-party web servers and databases for smooth operation. For late-breaking documentation updates, please consult the Errata directory.

Mac OS X

The latest release of Lasso 9 Server for Mac OS X 10.5 (64-bit Intel only), 10.6, 10.7, and 10.8 can be found here:

Download Lasso-Server-with-Instance-Manager-9.2.7.zip (32.2 MB)

IMPORTANT NOTE: X11 *must* be installed first, before installing Lasso 9 - [Direct Link to X11 Installer].

Once downloaded, expand the archive and run the installer which will guide you through the installation process.

Note for installing on OS X 10.8 and later

Upgrading from an earlier OS X: If you already have Lasso 9 installed, on first boot after upgrading Lasso 9 will try to start resulting in multiple X11 warnings. Clicking "Continue" will take you to an Apple page with a link to the X11 installer - [Direct Link]. It is advisable however to also reinstall Lasso 9 afterwards as Apple removes the Java runtime that is also required.

Installing Lasso 9 on Mavericks for the first time may also prompt an installation of an Oracle Java runtime. Be sure to instead install Apple's Java runtime from their support site.

The latest release of Lasso Server 9.2 for 64-bit Microsoft Windows can be downloaded with these links:

Apache 64-bit Lasso-Server-with-Instance-Manager-Apache2.2-9.2.7.exe

Once downloaded, run the installer which will guide you through the installation process.
