Hermetic Systems publishes 15 items of Windows software in diverse fields — those above plus others. This website also has many articles about calendars, cryptography and other topics.  Our flagship programs are our word- and phrase-counting software:
Hermetic Word Frequency Counter :  This program scans an MS Word docx file or a text file (including HTML and XML files, and UTF-8-encoded files) and counts the occurrences of different words. What is a 'word' is user-definable. The words found can be displayed alphabetically or by frequency (with file output for use with Excel). The program works with text in most European languages. Hermetic Word Frequency Counter
The Advanced Version :  This program does everything that the above program does and also counts phrases (optionally with pattern matching, thus enabling searches). It can process multiple files in multple folders in a single operation. Hermetic Word Frequency Counter Advanced Version

These programs run under all versions of Windows from Windows XP to Windows 8 (they can also be run on Macs which can run Windows). All are completely virus-free (as attested by VirusTotal). The free trial versions can be made fully-functional by means of an activation key after purchase of a user license. The key can be sent immediately upon purchase (or can be obtained immediately after purchase), so there's no waiting required. For some programs you can purchase either a 3-month license, a 1-year license or a perpetual license (and site licenses are available for some). Updates to new versions are free, as is tech support for the duration of the user license.
