Hardware and software requirements

This chapter contains information on these main topics:

• Supported server platforms
• Supported client platforms
• Supported languages

Note: Third party components and versions, such as operating systems, browsers etc., no longer in mainstream support by the third-party provider are not supported by Longview as well.

Supported server platforms

Supported platforms are defined as the Operating System and RDBMS “families,” and minimum patch/point level on which the application is supported under the terms of the Customer’s maintenance Services Agreement. Assistance with issue investigation and resolution is available through Support Services. Any platform related software issues identified will be addressed based on Longview’s standard issue prioritization criteria.

Longview reserves the right to end support for supported platforms with subsequent releases of the application.

Should a customer choose to use current versions of Longview software on non-supported platforms, Longview will continue to provide the application support under the terms of the Maintenance Services Agreement with the following exceptions:

• Issues encountered which cannot be replicated on a currently supported platform will not be addressed.
• For issues that exist on both supported and non-supported platforms, fixes will be verified only on supported platforms and may or may not address the issue on the non-supported platform.
• No support is available for platforms (O/S or RDBMS) that are no longer supported by their respective vendors.

This section contains information on supported platforms for the following items:

• Updating Windows Universal CRT
• Data Server OS and RDBMS
• Web Server
• Data Server Web Services
• Longview Grid Server
• HTTP Proxy Server

Updating Windows Universal CRT

Improved security and compatibility of Longview means that older server machines must install Windows Universal C Runtime (CRT) update 2999226.

You can determine whether your server requires this update and download this update, if needed, from the following link:

https://support.microsoft.com/en-us/topic/update-for-universal-c-runtime-in-windows-c0514201-7fe6-95a3-b0a5-287930f3560c

Data Server OS and RDBMS

The following combinations are supported for all servers in the application.

Note: If you are using a separate Database server, then any platform and Operating System supporting the database versions can be used.

Web Server

The following combinations are supported for the Web Server.

Note: The Web Server supports only x64 Server hardware architecture.

Data Server Web Services

The following combinations are supported for Data Server Web Services.

Note: Data Server Web Services supports only x64 Server hardware architecture.

Note: Apache Tomcat is deployed as part of the Data Server Web Services install process. If you have already installed Apache Tomcat, you must have version 9.0.16 installed.

Longview Grid Server

The following combinations are supported for the Longview Grid Server when Grid Processing Type is selected in Longview Server Manager.

Note: Longview Grid Server supports only x64 Server hardware architecture.

Note: You must install the ODBC Driver 18 for SQL Server on the grid node that corresponds to the RDBMS that the Longview application server is configured for.

HTTP Proxy Server

The following combinations are supported for the HTTP Proxy Server.

Note: You must have .NET 4.8 installed to run HTTP Proxy Server.

Supported client platforms

This section contains information on Supported platforms for the following items:

• Longview client components
• Microsoft Excel

Longview client components

The following platforms are supported for client computers.

Note: ¹ Chrome browsers require a Chrome extension to launch ClickOnce components. For example, the Windows Remix ClickOnce Helper to launch Longview ClickOnce components.
² Longview components require WebView2.dll which is part of Edge.

Note: Longview recommends a DPI display setting of 100%. Using a DPI mode other than 100% can cause display issues ranging from incorrect and inconsistent font sizes to interface elements not being visible on the screen.

Microsoft Excel

The following Microsoft Excel versions are supported.

• Office 365 – 32-bit and 64-bit
• Excel 2021 – 32-bit and 64-bit
• Excel 2019 – 32-bit and 64-bit

Note: Both Microsoft Office and Microsoft Office 365 are supported; however, you must use the fully deployed version of Microsoft Excel to work with Longview Add-In for Office

Supported languages

Longview client components are language consistent. For example, for a French client system, this update supports the French version of the Longview client, with the default regional settings, running with the French version of the respective operating system, and the French version of Microsoft Office.

However, for the servers, this update supports English versions of the respective RDBMS, server operating system, or Web server, regardless of the client language.

The following table outlines the language requirements for your Longview system.
