Quartus Assembler License Error: Unlicensed IP 56CC 2480 & 2493 in Bitec HDMI 2.1 eARC Demo

Hi,

I am currently working with the Bitec FMC HDMI 2.1 Daughter Card (Rev9) on an Arria 10 FPGA (using Quartus Prime 20.4). I am encountering a licensing issue when running the provided eARC demo (bitec_hdmi/earc).

The Problem:
The Assembler fails to generate the .sof file with the following error messages:

Steps Taken:

License Setup:
I have already added the following Bitec license files to the Quartus License Setup. The licenses appear to be active in the License Setup window, but the "Unknown 56CC" error persists during the assembly stage.

Quartus Version: I am using Quartus Prime Pro 20.4.

Questions:

1. Is there any way to run and generate the programming files for this Bitec HDMI eARC demo?
2. Is there a known compatibility issue between these IP cores and Quartus 20.4?
3. Are there any additional environment variables or settings I should check to ensure these encrypted files are properly recognized?

Any guidance or suggestions would be greatly appreciated.

Thank you!
