The latest 1.3.nnnn and 1.4.nnnn versions (new) of AfterMath use a data file format that is not backwards-compatible with any 1.2.nnnn or earlier version (old). Archive files saved to disk by old versions can be opened by new versions; however, data files saved to disk by new versions cannot be opened by old versions. We suggest that all computers using AfterMath should be updated to new versions ore all remain at old versions.


AfterMath requires that certain Microsoft redistributable libraries and third-party device drivers be installed on your system. The Aftermath installation process will verify that the proper version of Microsoft libraries are installed and prompt you to download them if necessary; however, it cannot detect which device drivers should be installed. Only the original installation media shipped with the instrument can automatically install the correct device drivers.

All Versions

Here we present all versions of AfterMath, including Beta (not yet fully released) and archived (older) downloads. We suggest the Current Release Version in most cases.
