VersionNT

The installer sets this variable to the Windows version number of the target system if the target system is Windows NT-based. Otherwise it is not set (or set to 0). The Windows version number is encoded as 100 * major + minor, as follows:

*Early preview versions of Windows 10 used Windows version number 6.4 (and corresponding VersionNTxx number 604). However, Microsoft chose version 10.0 as the official release number. InstallMate installers will recognize both 6.4 and 10.0 as Windows 10.

Usage

You can refer to it as <VersionNT>. In conditional expressions you can omit the brackets and use tests like VersionNT >= 500. Do not set this variable directly; it is set automatically when the installer runs.
