SigFit Application
The installers below include SigFit, Visual SigFit, interface support files, documentation, and release notes in an installation executable file. Tutorials and examples may be downloaded separately from the links in the section of links at the bottom of the page. To install, please follow the installation instructions. Please note that SigFit version 2026R2 requires license server software 11.19.9.0 and a new format license file while 2026R1 may run with either license server software 11.17.0.0 or 11.19.9.0 and an old format license file. New license files with both old format FEATURE lines and new format feature lines were emailed to current customers in early June 2026 and have _rev1 at the end of the base filename. These license files allow you to run either SigFit v2026R1 or v2026R2 until the old format FEATURE lines expire. If you are trying to upgrade SigFit to 2026R2 and you cannot locate your new _rev1 license file, then please contact Sigmadyne.
