FT4232H: Configuring RI# as TXDEN Using FTProg
The answer is right there in the very first screenshot - last Entry: 

EEPROM Type: No EEPROM detected


So it seems your design either has no EEPROM connected to the FT4232H or they are not correctly connected or compatible. If they are missing you can glue one on top of the FT4232H and use flying wires to connect them - had to do this myself once because I thought I would not need the EEPROM for my design but I was wrong. So I had to add one afterwards.
