In order to help you prepare for the future, we wanted to share our plan to change our system requirements in future versions of Relay. The following changes should be expected in future releases:

  • Dropping support for all 32-bit server operating systems including:
    • Windows Server 2003 (all editions)
    • Windows Server 2008
  • NOTE: We will continue to support Windows Server 2008 R2 (64 bit) and Windows Server 2012 (64 bit)
  • Dropping support for Microsoft SQL Server 2005 (all editions)
  • Dropping support for Microsoft Internet Explorer 7
  • Dropping support for Microsoft Office 2003 PowerPoint Plug-in
  • Elimination of Info Gathering Tool – to be replaced with in product information and graphs

Frequently Asked Questions

Q: Is TechSmith Relay Server compatible with the 64-bit version of Windows Server?

A: Yes. TechSmith Relay 2.0 or later, has a 64-bit version that operates with Windows Server 2008 64-bit and Windows Server 2012.

Q: Can I run TechSmith Relay in a Virtual Machine configuration?

A: TechSmith Relay may be run in a virtualized environment with the understanding that the CPU-intensive nature of transcodings makes it a good fit for a dedicated server. If given the necessary resources in a properly configured VM instance, it will work well. Running the TechSmith Relay server on an underpowered or multi-purpose VM is not recommended and will result in poor performance.

Q: Can I run other applications on the same server with TechSmith Relay?

A: TechSmith Relay is designed to run on a stand-alone server and not as an application on a multi-purpose server. Other SQL Server installations or instances, additional websites, or other non-standard software or web applications installed on the server may cause problems with the recorder (client) communication with the TechSmith Relay server.

Q: What should I do to prepare my server for installation?

A: It is recommended that you begin with a fresh install of Windows Server 2003, 2008, or 2012, install all related Windows patches, and then install TechSmith Relay Server. The software installer will walk you through the setup process.

Q: Do I really need 100+ GB of hard drive space on the server?

A: Yes. You need a lot of hard disk space because unprocessed recordings consume space until they are published (at which time the original recording is deleted). As a rough guideline, a 1-hour recording requires between 1-2 GB of space.

Q: What's the benefit of more CPU cores?

A: More processing cores means more simultaneous encoding potential, and therefore, faster encoding and publishing.

Q: Why doesn't TechSmith Relay use all available CPU cores for encoding?

A: TechSmith Relay reserves one core for overhead processes which yields faster encodings and publishing overall. For example, if you use a quad-core server, TechSmith Relay will encode 3 simultaneous recordings. This achieves the fastest performance, and is faster than if all 4 cores were dedicated to encoding recordings.
