The database server will run only on a 64‑bit version of Windows. Clients can be 32‑bit or 64‑bit.

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

Jade 2020 requires the Microsoft Visual C++ 2015-2022 Redistributables to be installed. Download the latest version from Microsoft, or use the version that comes with Jade. You must install the x64 redistributables to run a 64‑bit node, and the x86 redistributables to run a 32‑bit node.

Installation of the required C++ runtimes will be done as part of the normal Jade installation, if necessary. Installing this Microsoft redistributable package requires administration privileges.
