The website https://sites.socsci.uci.edu/~cragin/fsQCA/software.shtml offers the software fsQCA 4.1. It is still possible to do crisp-set QCA with that software. But you need to be careful using it because the way in which the Quine-McCluskey algorithm and the procedures for solving the PI chart are implemented in that software will regularly lead to situations where you will not discover all models that fit your data equally well. Among those models not revealed to you may be the one that represents the true causal story behind your data. In other words, no matter how good or extensive your data are, you will never be able to find the truth.
