Lasso Professional 8.6 for Windows Installation

Supported platforms

Lasso Professional 8.6 has been tested on 32- and 64-bit distributions of Windows XP Professional, Windows 7, Windows Server 2003, Windows Server 2008, and Windows Server 2008R2. Supported web servers are IIS 6, IIS 7 and Apache 2.2. 32-bit and 64-bit connectors are available for each web server supported.

Instructions for installing Lasso 8.6 and FileMaker Server 11 on 64-bit Windows are available.

Note: Windows Vista is not an officially-supported operating system.

Before installing

Important: Earlier versions of Lasso must be uninstalled before installing Lasso Professional 8.6.

Lasso Professional 8.6 requires the following Microsoft updates:

• Microsoft .NET Framework 3.5

  • For servers running Windows Server 2008R2, use Server Manager to add the Application Server role, which includes .NET Framework 3.5.1.

• Microsoft .NET Framework 4

• Microsoft Visual C++ 2010 Redistributable Package (x86)

• 64-bit systems also require the Microsoft Visual C++ 2010 Redistributable Package (x64)

• Servers running IIS 7 need ISAPI enabled. 

  • For Windows Server, use the Roles Wizard to add 'ISAPI Extensions' and 'ISAPI Filters' under Web Server > Application Development. 

  • For other Windows versions, open Control Panel > Programs and Features and click 'Turn Windows features on or off', then under 'Internet Information Services > World Wide Web Services > Application Development Features', enable 'ISAPI Extensions' and 'ISAPI Filters'.

Important: As it is a system-level service, Lasso Professional 8.6 must be installed & run under a user with administrator privileges to work correctly.

Important: By default Windows is set to hide file extensions for known file types. This may cause files that appear to have a .lasso extension to actually have a .lasso.txt extension. Be sure to first follow Microsoft's support article on how to show all extensions in Windows Explorer.

Installing Lasso Professional 8.6

Download the latest Lasso Professional 8.6 installer and run the included installer package.

If installing on 64-bit Windows with IIS: Lasso Professional 8.6 for Windows now provides a 64-bit connector for IIS on 64-bit systems, which is installed by default. To install, select the 'IIS Connector (Win64)' feature.
If installing on 32-bit Windows with IIS: When installing, select the 'Custom' install option, deselect the 'IIS Connector (Win64)' feature, and select the 'IIS Connector' feature (for IIS 7 and above) or the 'IIS 6 Connector' feature (for IIS 6).

• Navigate to the ImageMagick downloads page.

    • Downloads from the above site are at your own risk. LassoSoft Inc can not guarantee their contents nor their continued availability.
• Restart Lasso.

Note: The 32-bit ImageMagick binaries should be installed regardless of whether the operating system is 32-bit or 64-bit.
