Polyhedron Licensing System

Polyhedron Licensing System (PLS) – Version 1.5

Polyhedron Licensing System (PLS) is a simple but flexible package for controlling the use of licensed software without the expense or inconvenience of “dongle” or licence server systems.

PLS gives software vendors the ability to specify “hard” and/or “soft” forms of copy protection. For example a “soft” protection scheme might display the licensee’s name when the program runs, so that the source of pirated versions can be traced.  A “harder” scheme might involve checking that the program runs only when a particular hard disk is present.

In addition, PLS can be used to implement time-limited licences, for example for trial versions. Another option is to use PLS to enable selected facilities within an application.

PLS is extremely easy to use, both for the vendor and the end-user.  Licences are contained in small plain text files which can be emailed, or even dictated over the telephone. The licensed software itself may be distributed freely, but remains inoperative (or restricted) until a valid licence file is found. Any attempt to tamper with the licence file is detected by PLS.

PLS is available for Windows 95, 98, NT, 2000 and XP systems. Object code versions are supplied for Intel Visual Fortran, Compaq Visual Fortran, Lahey LF95 and Salford FTN95. In addition a DLL version, callable from Visual Basic, Delphi and other languages is supplied.

Our Account Manager, Stephanie, was fantastic in dealing with our questions and my colleague’s concerns (many thanks Stephanie!) and your colleague Joe has provided invaluable assistance to my colleagues and myself during our initial and extended testing phases of Reference Manager.

You have set a benchmark standard that many other companies should aspire to.

Huge amount learnt, much more than I expected. Appreciate the ability of the programme much more than I did before.

At 13-years old, my daughter’s research manuscript has been accepted for publication in a top tier peer-reviewed Environmental Science journal and OriginPro 8.6 will allow her to export the graphs in a wide variety of formats which can meet any publisher’s requirements. Kudos to OriginLab for designing innovative and intuitive software that can span the needs of both a burgeoning young scientist like my daughter to a PhD expert in their field. It is hard to imagine that other products offer this extraordinary level of user versatility.
