On the official website, the developers have specified that LabelRight is compatible with the following versions of Windows: PC Intel® Pentium® compatible CPU Running Windows 10, 8, 7, Vista, or XP - 32bit & 64bit compatible.
There is a download available on the official website, but it's not specified what version is it.
