Dependencies
From OpenSimulator
In addition to the OpenSim code itself, certain other packages need to be installed on different platforms in order to get OpenSim binaries to run.
As well as the information on this page (which should be expanded), you may find more information on dependencies in Build Instructions though this will also contain dependencies required only for building. This are also more hints in Troubleshooting
Windows
When using OpenSim on Windows XP ensure it is updated to at least Service Pack 2 (SP2).
When using OpenSim on Windows XP, VISTA, Win-7, Server 2003 & 2008, You need to have the newest version of the .NET Framework 3.5 sp1 (3.51), available from Microsoft Download Centre: www.microsoft.com/downloads/details.aspx [[|]]
