HLS Compiler and Quartus version compatibility and troubles with Visual Studio

Hi @alxb,

Thank you for posting in Intel community forum and hope all is well.
I believe you have installed the HLS 21.1 pro version and for that it does have backwards compatibility but are just until 17.1.1. (Please refer here for more details)

As for visual studio, HLS requires the C++ compiler (i.e. I believe is MSVC compiler) for it to work.
On the visual studio installation, I am not sure if putting it in D drive would impact the detection, but I would recommend to check on your environment path for the visual studio installation as scripts in the init_hls.bat is usually referring to environment variable.
Hope that clarify.

Best Wishes
BB
