From time to time, it becomes necessary for TaxCalc to cease supporting certain versions of computer operating systems. Usually, these are for reasons such as the developer of that operating system stops providing support or security updates.
When our official support stops, we stop testing the software on that operating system. It may be possible to run TaxCalc on unsupported operating systems but you do so at your own risk. Indeed, as time goes by, our software may completely cease to run and may do so without warning.
This article lists Operating Systems variants that are now unsupported by TaxCalc and how to move forward.
