Resources

All applications in versions prior to 4.0 are x86 processes. This means they work on both x86 and x64 operating systems, but since version 3.0 we have always recommended x64 bit OSes in order to allow for larger amounts of system RAM.

Windows Server

All applications will run on the supported versions of Windows Server. However, we do not recommend running Sentinel (the UI client) on a server. This is because the OS and server hardware are not designed to support client applications with sophisticated user interfaces. Sentinel makes use of video acceleration hardware and the associated software drivers. On a server these features are either missing or not good enough to run Sentinel smoothly. This does not prevent Sentinel being used for commissioning or the occasional configuration change on a server but should not be considered for permanent use by operators.

If you must run Sentinel on Windows Server then non-admin users are not supported. You can only run the client as a local or domain administrator.
