I had the same problem.

I solved it like this:

  1. Opened the QPF in Intel/Quartus Prime.
  2. Attempted to auto upgrade the IP. It failed, but it advised me to manually do the upgrade in Platform Designer. That worked.
  3. Compiled it.
  4. Downloaded it.

There is also a bug in the batch file. You need to replace the double backslashes \\ with single backslashes \ and you might need to change bin to bin64:

@ REM ######################################
@ REM # Variable to ignore <CR> in DOS
@ REM # line endings
@ set SHELLOPTS=igncr
 
@ REM ######################################
@ REM # Variable to ignore mixed paths
@ REM # i.e. G:/$SOPC_KIT_NIOS2/bin
@ set CYGWIN=nodosfilewarning
 
@%QUARTUS_ROOTDIR%\bin64\quartus_pgm.exe -m jtag -c 1 -o "p;DE2_115_Audio.sof"
@ set SOPC_BUILDER_PATH=%SOPC_KIT_NIOS2%+%SOPC_BUILDER_PATH%
 
@ "%QUARTUS_ROOTDIR%\bin64\cygwin\bin\bash.exe" --rcfile ".\DE2_115_Audio_bashrc"
