Versions Before 2021

Help files for Datacor Flow Simulation products released before 2021 are provided in an offline *.chm format which is included in the installation folder for the product (by default in the C:\AFT Products folder). Help files may be launched from within the software via the Help menu, or by directly launching the *.chm file. Note that *.chm files cannot be launched from network locations due to Microsoft's firewall settings, and therefore must be copied to the local machine to appear correctly.
