30-day Evaluation Licence (Windows)


A trial version of Winteracter is available for use with one of these Windows Fortran compilers:

  • Absoft Pro Fortran 11 onwards
  • Intel Fortran 11.0 onwards (Intel Visual Fortran through to Intel oneAPI)
  • Lahey/Fujitsu Fortran 5.7/7.x
  • GNU gfortran 4.7/4.9/5.x-13.x (MinGW) (including Lahey/GNU Fortran)
  • Salford/Silverfrost FTN95/Win32

The evaluation licence can be installed on 32-bit or 64-bit Windows operating systems. Depending on the chosen compiler, it can be used to produce both 32-bit and 64-bit Windows executables.

We recommend that potential purchasers run the main Winteracter demo first, before requesting a trial version, since the demo provides a concise illustration of most Winteracter product features.

A 30-day Winteracter (Evaluation) licence can be requested via the link below. If your evaluation licence request is approved, installation codes will be sent by email. These will allow the trial software to be used for up to 30 days from the date that the Winteracter (Evaluation) licence is issued. The evaluation version is available as a single file download (approx 50mb), supplied as a self-extracting Windows executable. Note: We do not currently offer evaluation versions for other platforms.

What Is Included ?

A Winteracter (Evaluation) licence includes time limited, but otherwise fully functional versions of the following core Winteracter components:

  • Winteracter library for a specific compiler.
  • Winteracter Development Environment (WiDE).
  • Documentation, including the Programming Guide, Programming Reference, WiDE help and OpenGL reference.
  • A substantial selection of example programs.
  • A sample selection of stock images (icons, cursors and toolbar buttons).

Terms and Conditions

  • Evaluation is strictly subject to the terms of the Winteracter (Evaluation) Licence Agreement.
  • Support is available via email covering basic "getting started" issues and references to appropriate documentation. ISS reserves the right to vary the nature, availability and lifetime of this free service at our sole discretion.
  • Executables built with an Evaluation licence will display an "evaluation version" message each time the program is run. This message does not appear in programs built with the full retail product.
  • Executables built with an Evaluation licence will cease to function upon expiry of the evaluation period.
  • The trial version is mainly provided for the benefit of new customers. We do not recommend installing a Winteracter (Evaluation) licence on the same system as an existing full Winteracter licence.
  • ISS reserves the right to decline any evaluation request at our sole discretion. In particular, requests for multiple evaluations, repeat evaluation periods or evaluation extensions will not normally be accepted.
