Release Notes


This release rebuilds the viewer using 64bit address space. It is our hope that this will improve viewer stability, allow you to use more of the memory in your system (if you have more than 4GB), and possibly also improve performance. This latest update includes improvements and bugfixes to address image handling crashes (thanks to Kitty Barnett for her contribution) and installer / updater weirdness.


There are now separate 32-bit and 64-bit builds for Windows.

  • If you use an HD 2000 or 3000 series video card on Windows 10, choose 32 bit
  • Otherwise, choose the one that matches your copy of Windows

If your computer can run 64bit, and most can, you will get better performance and fewer crashes running a 64 bit Windows and Viewer. If you chose the wrong one, the viewer will upgrade you again the first time you run it to the correct one (if you think it made the wrong choice, please file a bug in jira). This build further refines the determination of what is "the best" platform for your system.


The Mac build does not support 32-bit Macs (this is permanent, and not really a change since it's been some time since we supported OS X versions that would still run on a 32-bit system).

  • This build shows two icons on the Dock when running. The first one is a new launcher/monitor process (SL_Launcher) that checks for updates; the second is the viewer itself, but both are labelled "Second Life Viewer". If you are going to pin the icon on the Dock, pin the first one or you'll get a warning each time you launch. We hope/plan to get this sorted out so that only one shows.
  • Video media (QuickTime) usually does not play (the media handling is now the same as the Windows viewer).
  • The volume of web based media (e.g. YouTube) doesn't change based on your distance from the source.


There is no Linux viewer yet. We hope to begin work on addressing this with the community after the release of the Mac and Windows versions.
