The database server runs only on a 64‑bit version of Windows. Clients can be 32‑bit or 64‑bit. Any node that hosts a JADE 7.1 database must be 64‑bit, including single user application servers and single user standard clients. The 32‑bit clients that are available are multiuser clients (application servers, presentation clients, and standard clients) that connect to the 64‑bit database server.

JADE encodes Unicode characters using the wide‑character‑encoding routines provided by Microsoft Windows.

JADE 7.1 has been compiled using Microsoft Windows C++ 2013 update 4 compiler for 64‑bit and 32‑bit binaries. It requires the Microsoft C++ 2013 (12.0.21005.1) Redistributable Package (x64) called vcredist_x64.exe or the Redistributable Package (x86) called vcredist_x86.exe to be installed. (This executable is supplied on the JADE distribution media.) This redistributable package should be installed on your Microsoft Internet Information Server (IIS) server if jadehttp.dll is used, to ensure that jadehttp.dll can execute correctly.

Installation of the required C++ runtimes will be done as part of the normal JADE installation or upgrade process. Installing this Microsoft redistributable package requires administration privileges. Alternatively, you can deploy this package to all workstations before installing or upgrading to JADE 7.1, using the appropriate techniques that allow for privileged installations.

Although minimum Service Pack (SP) levels are specified, we recommend that you keep up-to-date with Service Packs and security updates for the operating system that you are running.
