Apologies for late response,
The Intel HLS Compiler is included in the Windows release of Intel Quartus Prime Design Software Version v17.1.
However Patch is created for 18.1 Pro. You must either have previously installed the Quartus Prime 18.1 software or must install the Quartus Prime 18.1 software before installing this patch. Otherwise, the patch will not be installed correctly and the Quartus Prime software will not run properly.
