The print server log file shows error: "Class not registered" whenever connecting to the Fiscal printer's COM port, even after installing FPAX_TZA700 COM Server and running Datecs_Install_2012_07_01v1_0_0_8 installation. This generally happens at Tanzania sites that use Fiscal printers.
Cause of this is that there is a class that in included in the installation for FPAX_TAN2000 COM Server installation.
To fix this, uninstall all FPAX installations from Programs and Features, then install the FPAX_TZA700 COM Server, then FPAX_TAN2000 COM Server, running both installation files as "Administrator".
This will make the print server open with all needed classes and enable you to use the Fiscal printer as normal.
*This post applies to all V4.8.x print servers.
