Do not set this variable directly; it is set automatically when the
installer runs. |
| How to use |
You can refer to it as <VersionNT64> (Tarma native syntax,
preferred) or [VersionNT64]
(Windows Installer syntax). In conditional expressions you can omit the brackets and use tests like
VersionNT64 >= 500. |
