Hi @GabrielMarco,
Thank you for posting in Intel community forum and hope all is well.
Based on the error mention it seems that you might have missed some other required software, which I suspected it maybe the 'FPGA Support Package for the Intel® oneAPI DPC++/C++ Compiler' (https://www.intel.com/content/www/us/en/developer/tools/oneapi/fpga-download.html?operatingsystem=windows&windows-install=offline). More details of of which software is required you can refer to the oneAPI handbook in the link below:
- https://www.intel.com/content/www/us/en/docs/oneapi-fpga-add-on/developer-guide/2025-0/installing-the-intel-oneapi-fpga-development.html
And once all is installed would recommend to refer to steps #5 in the link above to set the required environment variable. Once all is set you will be good to go.
Note: Also here is the link is system requirement for the oneAPI tools (https://www.intel.com/content/www/us/en/developer/articles/system-requirements/oneapi-dpcpp/2025.html)
Best Wishes
