  • Windows 8 Desktop Mode (PC)
  • Windows 8.1
  • Windows 7

  • Windows Server 2016

Note: Windows 8 User Interface mode is not supported whether you're using a PC or a tablet computer. The version of IE 10 for Windows 8 User Interface mode doesn't support installation of the Relativity viewer.

Relativity Desktop Client

The Relativity Desktop Client (RDC) is a utility used for importing and exporting documents, images, natives, and productions. This utility requires the following software:

  • Upgrade to Microsoft .NET 4.6.2 to install the latest version of RDC. You must also install Microsoft Visual C++ 2015 Redistributable.

Note: Visual C++ 2005 SP1 Redistributable x86 is supported on 32-bit and 64-bit OS, but x64 is supported on 64-bit OS only.

For detailed installation instructions, see the Using the RDC installer.

RelativityOne Staging Explorer

The RelativityOne Staging Explorer option enables you to upload files to a staging area for RelativityOne or to download files from your RelativityOne storage location to a local computer. This utility requires the following software:

  • Install Microsoft Visual C++ 2015 Redistributable.

Supported browsers

The following browsers support Relativity:

Note: As of August 31, 2017, we no longer support Internet Explore (IE) 10. Please upgrade to a compatible version of IE 11.

RelativityOne supports the following Browsers:

Browser requirements RelativityOne
IE 8 (32-bit) Not supported
IE 9 (32-bit) Not supported
IE 11
Chrome (for Windows and Mac OSX) 3 latest browser versions at time of release
Firefox (for Windows and Mac OSX) 3 latest browser versions at time of release
Safari (OSX 10.9) 2 latest browser versions at time of release
Safari (OSX 10.10) 2 latest browser versions at time of release

We recommend using the latest version of Chrome, Firefox, and Safari with RelativityOne. For Chrome, Firefox, and Safari web browsers, RelativityOne supports:

  • The three most recent versions of Chrome and Firefox (for Windows and Mac OSX) at the time of a given Relativity release
  • The two most recent versions of Safari included with Mac OS X at the time of a given Relativity release

Note:  RelativityOne does not currently support the Linux operating system for any browser.

Note: Although IE11 and Firefox are currently supported in Relativity 9.6, performance testing indicates that they are slower when rendering the List Page in Relativity. IE11 is slower at DOM manipulation in the browser making it less performant in the HTML5 Viewer. For these reasons, we recommend using Chrome.

Note: Microsoft Internet Explorer 10.x (32-bit) is supported only on Windows 8 for Relativity 7.5.630.50 and later. In addition, Relativity doesn't support Internet Explorer 10 and 11 with Compatibility View.

Windows 8

There are two versions of Windows 8:

  • Windows RT - this version of Windows is optimized for ARM processor-based tablets and PCs. Relativity does not support this version.
  • Windows 8 Pro - this version runs the full Windows 8 software, so it can integrate with your existing infrastructure. This version is supported with Relativity 7.5.630.50 and later. Make sure you're running in Desktop mode with Compatibility View disabled in Internet Explorer 10.

JavaScript errors with IE10 and Windows 7

If you're using Internet Explorer 10 with Windows 7, you may encounter certain JavaScript errors like the following while running Relativity:

These errors can occur on the document review page when HTML-enabled fields are present on the layout. They can also occur when the stand-alone viewer is launched. These errors don't affect functionality. If you click Close on the error dialog, the error disappears and you can use Relativity as normal.

To resolve this issue, perform the following steps:

  1. Open the Internet Options window, and then select the Advanced tab.
  2. Deselect Display a notification about every script errorin the Browsing section.
  3. Select Disable script debugging (Internet Explorer).
  4. Click OK.
