Starting with Firestorm release 5.0.11.53634, Windows and Mac 64-bit versions are also available for Second Life with Havok support.

Older Firestorm 64-bit versions currently do not include Havok support. This means that:

• you will be unable to edit a region's navmesh;
• you cannot specify all physics properties or use convex decomposition for mesh uploads.

Older 64-bit versions therefore are OpenSim versions; they can be used both in SL and in other non-SL grids.

The 64-bit version of Firestorm can only be installed on 64-bit operating systems; it will not work on 32-bit. If you are not sure which you have, check in top menu, Help → About Firestorm. This will indicate whether you are on a 64-bit operating system. Examples:

• Windows: OS Version: Microsoft Windows 7 64-bit (Build 7600)
• Mac: Mac OS X 10.9.0 Darwin 13.0.0 Darwin Kernel Version 13.0.0: Thu Sep 19 22:22:27 PDT 2013; root:xnu-2422.1.72~6/RELEASE_X86_64 x86_6
• Linux: OS Version: Linux 3.8.0-30-generic #44-Ubuntu SMP Thu Aug 22 20:52:24 UTC 2013 x86_64

Note the “64-bit” and “x86_64” in the above.

If you attempt to install it on a 32-bit system, Windows users will get an error as shown here. Linux users will get errors on trying to run the program.

If you have 4GB RAM or less, there is no benefit to installing the 64-bit version of the viewer.

If you believe you have found a bug, then please report it as usual; information on how to file a bug report is given on this page. Please be sure to indicate in the title of the report, that the bug affects the 64-bit build, and don't forget to give your system information in the Environment field. Also, it would be helpful if you could verify whether or not the same problem occurs with the 32-bit build of the viewer.

Currently, if you need to reinstall the 64-bit version of Firestorm, you will first need to remove the existing copy manually, via Add/Remove Programs. Note that the 64-bit version identifies differently from the 32-bit, as follows:

• 32-bit: Firestorm-Release
• 64-bit: Firestorm SecondLife and OpenSim viewer

So if you have both installed, be careful to remove the correct one.

Below are some issues that some people have run across during testing, and solutions or work-arounds.

If you get the error “The program can't start because MSVCP100.dll is missing. Try reinstalling to fix this problem.” when starting the 64-bit version of Firestorm, you will need to install the package containing this file. Go to this page, download and install both the 32-bit and the 64-bit versions.

If you get this error during install, then the steps (from the JIRA referenced above), as as follows:

1. Clear Temp directory.
2. Locate the .msi that you downloaded.
3. While holding down the Shift key on the keyboard, right-click on the msi file, then choose Copy As Path.
4. Go to Start > All Programs > Accessories.
5. Right-click on Command Prompt and choose Run As Administrator. This should open a command prompt window, labeled “Administrator:”.
6. In the Command Prompt window, type msiexec /i (you need to enter a single space after “/i”).
7. Right-click in the Command Prompt window, then choose Paste. This should paste the path to the MSI file that you copied in Step 2 above.
8. Press Enter to run the command.
