Concordance, text analysis and concordancing software, was launched on 1 January 1999 and became unavailable for download or purchase on 1 January 2016 because of compatibility issues after then-recent updates to Windows. I shall not be able to offer a revised version in the future.

Support for Concordance is ending

26 years after it was published and 9 years after it ceased to be on sale, Concordance is nearing the end of its support period.

Registered users (that is, those who purchased from me a licence to use Concordance when they were on sale) may continue to use Concordance indefinitely, but should note that all support, including replacements for lost registrations or a lost installer, will not be available after a date that will be no later than 1 January 2026 and may be sooner. Therefore registered users should ensure they have their own copies of their registration and the installer safely stored on a reliable backup medium, especially if they plan to move to a new computer in the future.

Registered users of the software may get in touch if necessary. This is a new email address as of January 2023.

If you did not purchase a licence to use Concordance when it was on sale, please don't use your valuable time asking me whether you can now obtain the software, as the answer is no.

I thank all registered users for their kind and courteous support over the 17 years Concordance was in widespread use in more than 70 countries.
