VersionNT64 property

The installer sets the VersionNT64 property to the version number for the operating system only if the system is running on a 64-bit computer. The property is undefined if the operating system is not 64-bit.

The value is an integer: MajorVersion * 100 + MinorVersion.

Remarks

Conditional expressions test for 64-bit Windows simply by using the property name, or by verifying the version using a comparison operator.
